Proficiency swap bug.

Hello, is there any solution how can i swap the Axesmith for Hammersmith ? I did wrong choice with that and now if i wish unlearn the axesmith the error message will pop up with words ''You can't do that right now''. So my question is: When will i be able to change the proficiency ? It's rly bad cuz i have my DrakenFist Hammer in inventory and cannot wear him cuz of this bug with proficiency swap. And btw unlearn whole weaponsmith is bugged too so im stuck in this situation without any solution and GM didnt answer on my ticket in game for week. So i beg you, pls change my proficiency from Axesmith to Hammersmith or repair this bug. Thank you Warmane!
