Werewolf Temperaments not removing upon removal of Werewolf trait

I am having an issue with removing werewolf Temperaments from my sim, who's no longer a werewolf. I've tried everything and nothing is working. This is very annoying every time he swims or showers because it makes him very angry for 2 sim hours! Can we get a glitch fix for this, too, EA? When removing the trait, it should remove ALL attachments to the Werewolf form! I recently bought this expansion but it is proving to be a royal pain in the butt, imho.
