Switching preferences doesn't undo disliked item

Didn't assign decor preferences, then my sim developed a dislike for an item in the house that actually aligns with their intended aesthetic. Switched all their decor preferences to liked, but my sim still gets enraged while sleeping. I don't know what the item is. How to I A) find out what item is causing this and B) get rid of the dislike? Is there a cheat? It would be cool to see a list of the items my sim likes and dislikes. I would also love to keep eco footprint without having to deal with my sim developing dislikes.
