Trait Potion Gave No Exp?

Describe the problem. Be as specific as possible!:
Trait Potion claims my Charm Level Increased Significantly, but Charm doesn't gain exp. This has happened before at least once and that was before my Charm was past lvl 30. I'm unsure whether I have this problem only with charm or if other traits didn't increase either.

However I'm 100% sure Charm didn't increase, because it only has 206 exp and that isn't a "significant increase" now is it?

Hard to prove with pictures. Should've taken a SS before using the potion to prove this, but if trait potion adds to the daily exp, then I guess these pictures prove it:
