Storm Wave not working

Hello fellow gamers,

I have a problem with my skill gem storm wave all of a sudden.

Skill Requires Lvl 52, 66 Dex, 66 Int and quarterstaff

I'm lvl 61, 120 Dex, 74 Int with an equipped quarterstaff.

My Storm Wave is gone from the action bar. I can't drag it there anymore and when i click the detail arrow on the skill it states that it is currently unavailable.

I have tried taking all support gems out, relogging and switching the gems around.

Can someone please help me?

I can use a new storm wave skill gem but with only 2 support slots. The other skill gem just seems broken.
