Cross-bar not Locking?

[Umo]

lock the cross bar by clicking the lock icon

So what I'm saying it I can still edit my crossbar even though it's locked

Um... I feel I'm not understanding your question, but I'd try anyways: you can lock/unlock your cross-bar whenever you want, so you can customize it everytime you may see fit (obviously). Just unlock it again (click on padlock icon for opening), rearrange your skills and lock it again once you're finished (click on padlock icon for closing).

PS. I still think I'm missing something here...

EDIT: Oops, the issue is your controller is not working properly anymore?
