Issues in CAS after household is already in town

I have tried to edit a household and I keep running into the same issue with the pets pack, everytime I edit a household that’s already in the game that has an animal after a while I go to edit the household and once I finish editing my sim when I click to play the game it’s taking me to the pet in the household and saying the breed isn’t filled out. I’ve ran into this issue since before the blast from the past release and was wondering if anyone else is running into this issue? Playing on Xbox console with no cheats.
