Mystery Talent Bug Aim

So i have a Stabbey and got a Mystery Talent Aim.

We All Know that Mystery Talent Aim always Activates on the start of a Battle,

everytime i teach my Stabbey a new Skill , the Mystery Talents gets bugged as if it was Disabled, not activating at the start of battles and stuff..

and have to re activate my mystery talent everytime i teach it a new skill..
