This bug has been an issue for me for years. I don't know if it's actually a bug or I don't know if I'm doing something wrong, I've taken out all my mode and it still happens. My household holds 8 people, and I have some sims I want to keep out of some rooms. I choose lock door for specific Sim and everyone shows up except one Sim. I changed the door, I changed who is locking the door, this one Sim just refuses to be locked out. I've had this happen to other Sim households, I don't know why this is an issue.

@ShootUpSatan Is the Sim a household Sim ?

Did you always play the same Sim or was it a different Sim each time ?

@ShootUpSatan Is that specific sim on the lot at the time you try to lock them out? If not, they don't show up on the list.

Yeah they're on the lot, and in my household. It's always the same sim

@ShootUpSatan Have you tried if it works for the same Sim in a different save game (For testing) ?
