Issues Removing Personal Traits

Hi my lovelies! So I'm having an issue with changing my sims traits. First off, I'm not a newbie when it comes to playing the sims. I'm good with cheats and what not. I know you can put in testingcheats true, add cas.fulleditmode, and then click the sim and go to modify. However, my circumstance is a little different that doesn't allow me to modify my sim in the fashion. I have a mod in my game that allows me to have more than eight sims in a household. So if I go to modify them normally, it deletes some of my house members. So, I'm trying to find a way to remove a personal trait that doesn't require going into CAS.

Also, by personal traits I mean things such as creative, foodie, cheerful, etc.

I've tried using the traits.remove_trait and then adding creative to the end of it, but it doesn't remove the trait. So...am I doing something wrong? If so what can I do?

Any help would be so much appreciated. :blush:
