why is my sim wearing swimwear to exercise

[BluePushyHawk]

So, I have had my sim go on a walk and a jog with their dog. The first time they put on their workout outfit, but now they want to wear their swimwear and I don't know why. I play on Xbox One and have a few DLC content installed: Highschool Years, Werewolves, Seasons, Growing Together, Cottage Living, Horse Ranch, Get Together, Get to Work, Cats and Dogs, Parenthood, Eco Lifestyle, Tiny Living, Nifty Knitting, Paranormal, Laundry Day. I have most recently installed the Paranormal Pack, but that was a few weeks ago before this started happening.

Hm. First, I'd suggest double checking your Sim's outfits to make sure you didn't end up using the same items in both by overriding the filter when you were making outfits. Otherwise, is there somewhere you've told Sims to walk/jog to that involves going through water? (Like that one very shallow stream in Horse Ranch.)
