See picture. I got Leadership to level 3 but it didn't unlock the task slot that says "Get any profession to level 3". Note that I am doing this through the gateway and perhaps it is a gateway bug, but I'm at work atm and can't check in game. Either way its a bug.

Might be worth logging in the main client, and logging out and back in to Gateway. I know that sounds like a cop-out answer, but it does help a surprisingly large amount of the time. Let me know if that doesn't help, it might be an issue with Gateway.
Along with one that would not complete.
