I’ve seen that happen before. I don’t think it’s serious. For some reason, the game is just calling multiple iterations of the same Sim. Do a move out/move back in and see if it fixes it.

I hope that’s all it is. D: I’m reloading now (even though this should be my sign to go to bed for tonight…), so I’ll do a quick move out/move in and see if the problem persists.
