POE2 Skill is not valid for this weapon set bug

Does anyone know a fix for this bug I upgraded my sceptre and now my skeleton cleric skill is bugged with this error. Also the passive skill from my sceptre doesn’t summon any skeletons either, I’ve tried everything I can think of.

Happen to me too, when I got a new skill grim feast and my skelaton cleric said skill not valid for this weapon, so what I do was I put the primary weapon into the second diary weapon and it work again, there should be a fix for this but so far that is the fix for me
