Traits removed via cas.fulledit don't really go away. This is a known bug that's been around since the game first came out. I doubt they'll prioritize fixing it anytime soon since it's a cheat-bug.
To fix it you'll have to go through and remove each of the traits individually by doing the following:
Use the Cheat Console by pressing CTRL+SHIFT+C. Input the cheat code testingcheats true. The type traits.remove_trait {TraitNameNoSpaces}
I have done this recently and it did remove them fully so hopefully it will work for you as well. If it doesn't try repairing your game to see if it fixes it. If it doesn't try removing any mods and try it then to see if you're having mod-conflict.
