High Self Esteem Trait Gone

Hello! So, long story short, my sims was corrupted when she aged from a child to a teen. After lots of back tracking, I managed to save her but I had to age her up in CAS, meaning she went from having High Confidence to nothing. Is there any way to add the High Self-Esteem Trait back in? I've tried traits.equip trait_high_self_esteem (and other variations) but it doesn't work so I figure that's not the right cheat.

I do have the updated version of MCCC, so if I can do it through there I'd love to know how! Google hasn't given me any answers yet since the pack is so new and I'm usually pretty good at working my way through this stuff, but I'm at a total loss on this one.
