Can't learn jobs

So I'm a level 16 Worgen and for some reason I can't learn any professions. When I try to learn a profession I click on the gathering or production and choose the job I can't learn it. When I click to learn it or to learn the profession that goes whit it or to browse the others nothig happens. I have tried the WTF, Cache and Interface Old thing and reopening the game but it doesn't work. Pls help.

The Jack of all trades npc is not working as intended and the report exists already
