Its happening to me too!! Im trying to make Elderberry Households and it keeps saying Im using packs that aren't present in either the lot they're living in or their clothes/facial features. I've gone through and checked every single item several times with filters. You can find my households under SenseiAeris. Elderberry 2nd Gen should only have base game, DU, and ROM items (yet shows blank GF pack and a random legging from JA). My Humble Spellcaster Home does show the proper amount of packs .

I made a base game Sims and she's showing two packs that I haven't used in creating her. I even went through her aspirations and traits to make sure they're only base game ones but she's still showing the packs. I went through all clothes, make ups and hair styles to find the wrong ones but didn't find any. They're all marked as base game items. I have also not played this Sim at all but saved her straight into my library and uploaded into the gallery. I made her yesterday and noticed the packs today.

I'm not sure if anyone has mentioned this fact. I can't remember the exact date of the update that this happened but I think it coincided with the time when base game was being given away free. EA went through all of the other stuff, game and expansion packs, picked items from many of them and then reclassified those items in both CAS and build as base game. The problem, I believe, is connected to that change. My assumption is EA did not update all of the EA game tags, filters, labels, etc. in all necessary areas of code. It is those specific items that were once in paid for packs that are still showing up as belonging to the pack they originally came from. Somewhere the game is still recognizing those specific items as coming from the packs they were in originally. That's why the game uploads will show the "other packs used" icons. Technically we are using the item that came from that pack but that item is now officially a base game item. It's extremely challenging to create base game only sims and builds with this error in play. Please look in this direction for the answer and I hope this issue will finally be fixed.

I've also been having this bug popping up more frequently lately. For me, it usually seems to happen when I'm making sims or a build, put something down, then decide I actually don't want to use that pack and delete/change the item, but the gallery item will still think it's there. But sometimes the gallery will insist that I've used an asset from a pack that I never used for the project and never would have used for it. I've also been cursed many times with blank lists of items used when I'm definitely not using a trait/lifestate or something else that wouldn't show up in the game. For me, accessories (especially the men's socks from get famous) and shoes tend to "stick" the most in cas, and smaller decorative items and columns tend to stick the most in builds.
I hope the devs fix it (and would love for them to also say which sim is wearing what item and also fix the blank lists to show debug items, traits, lifestates, etc). Until then, here are some ways I've been able to work around the issue on PC. I don't think the first option will work on console but the other two in-game options should be available to console players.
Fixing Your Stuff By Quitting the Game (what I've been defaulting to lately. Looks longer but has a 100% success rate so far)
1) Make sure your thing is saved to your library (it should be since that's how you realized it was wrong)
2) Go to Options, turn off your CC/Mods if you have them, and quit the game
3) Disable the packs you don't want in the thing you're trying to save. (I don't know if I'm allowed to link to this but James Turner's website has a tool where all you have to do is click to select the packs and then copy/paste for 3b
3a) Origin > My Game Library > [right click] Sims 4 > Game Properties > Advanced Launch Options
3b) In Command Line Augments, type in (without quotes) "-disablepacks:" and then the string of what you want to disable. It's formatted with EP/GP/SP and then the number it was in relation to its category when it was released. So "-disablepacks:EP01,GP01,SP01" (with no quotes spaces anywhere) would disable Get to Work, Outdoor Retreat, and Luxury Party stuff. If you don't know the pack order you can find a list in chronological order on wikipedia.
3c) Save
4) Launch the game
5) Create a New Game (this just ensures nothing breaks in your saves with all your packs installed. If you want to live on the wild side, you can go into one of your old saves)
6) Put down your build or open up CAS and bring out your household. It will give you a "Purchased Content Not Installed" warning, but click the check mark, then click Okay when it tells you items were removed.
7) Double check your creation to make sure you didn't lose any objects/terrain paint/wallpaper/accessories/pants/hair you actually wanted to be there.
8) Save your family and make sure the item is fixed.
9) (Enable CC/Mods if you had them) Quit your game.
10) Follow step 3a, this time deleting everything you typed in Command Line Augments for 3b. Save.
11) Launch your game and enjoy!
Fixing CAS Without Quitting the Game (hasn't been as effective for me lately :/ but hopefully it'll work for you)
1) undo all the relationships with other sims in the household (not always necessary but sometimes it prevents bugs later)
2) make a "twin" of every member of the household (I'm not sure if there's an option for this with pets since I don't play with them)
3) delete every member of the original household
4) redress/trait/relationship the new clones
5) cross your fingers and resave and check
Fixing Builds Without Quitting the Game (more successful than CAS, but can require a lot of troubleshooting)
1) save all the rooms to your library
2) check to see if every room says it uses the offending pack or just one. If every room is "infected" skip to Fixing With Quitting, if only one or a few rooms are infected, you've still got options
3) delete the offending room(s) and resave the lot to your gallery to see if it's still mistagged
4a) if deleting the offending room(s) fixed the save of the entire build, rebuild those rooms from scratch onto your base
4b) if deleting the offending room(s) did not fix the save of the entire build, bulldoze the lot entirely. Save the game. Save the lot to see if it shows only base game. Place all the "uninfected" rooms down as they should be and rebuild the offending room(s).

I believe at least SOME of the gallery issues could be solved by EA creating a way for us to clear our profile comments without having to do them one by one. A clear all button would be much appreciated!

Hey all, I know i might be a bit late to the party. Ive been having this problem too since i returned to the gallery. One thing i think people might have missed is Terrain. I spent over an hour going through my whole build that i was hoping to be completely base game, only to realise when i deleted the whole build to start from scratch, there was some terrain paint underneath from Get Together -.-
Hope this helps!
Happy Simming :D

One thing I have noticed whilst playing the game is, there are items (mainly in CAS) to which I don't have access, especially job outfits, which are kept as being used forever, even though I can't see them used by my Sim in CAS. I once created a vanilla Sim in CAS, raised up several skills and while doing that, saw in My Library that my Sim is or was wearing stuff from another expansion pack. In matter of fact, there was even a base game job outfit that was randomly used in combination with one DLC part and remained as being used from that point on. So these are some examples that I recall without having to look up in my saves:
◆ Astronaut outfit in combination with Get to Work shoes (why on earth only shoes!?)
◆ Veterinarian outfit, once used, never to be erased despite quitting the job
◆ Graduation outfit in DU in combination with Spa Day shoes (why always shoes!?), once used, kept forever
◆ Secret Society outfit, once joined in DU, never to be erased even after graduating
After realizing that, I am avoiding having my Sim ride on a rocket, cure pets, attend graduation day and join the Secret Society in order to keep my saves clear from DLC stuff. I am pretty sure that there are other job related outfits that stay forever on a Sim.

I've been having this issue well, and a similar issue where I see a build on the gallery that CLEARLY is using a pack (Eco Lifestyle for example) but the gallery shows it as not having used any packs.

I have tried testing around with a friend who has more packs than me, and we've found out similar cases than Japanic2012: some situational, non-player chosen outfits somehow get "stuck" on Sims and exported with them on the Gallery despite being nowhere to be found in CAS–even without any mods or cheats. But it seems that we have multiple bugs with different symptoms.
For CAS, we noticed the following:
EDIT: Seems like it also affect bottom-only CAS items which include shoes, including StrangerVille's Military cargo pants which have boots attached to them.
Also, per Japanic2012's later post, one does not need to enroll into the base game's Astronaut career to get an Astronaut suit with random DLC hidden shoes. Simply board a fully-built rocket.
For Build mode, we've seen the following:
All in all, it could be multiple problems with a large variety of symptoms that can even combine with each other :-/ Random hidden shoes on full-body career and situational outfits, synced hairstyle and make-up loosing sync with career outfits, career and situational outfits getting stuck and exported with the household, unlockable CAS parts not always flagging the household with their pack of origin, the CAS and Gallery interfaces not marking pack-specific swatches the same way, unlockable and crafted items not always flagging their pack of origin, and architectural elements other than doors, windows, floors and wall coverings which flag the pack without appearing in the Gallery. There's unfortunately quite a lot happening here :-(
EDIT: Typos, clarifications in the different "How-to"s, more typos, grammar, touchups for some observations.

I had a similar issue of the gallery stating I had used a pack but not showing any items listed. When I went back into my build and checked each item placed, I noticed that it was the stairs that were from a pack I wasn't planning on using (I was doing a base game only build). It seems that the list of items in the gallery only shows buy objects and not build items, but it really should show any type of item from a pack
