Keymap, Broadcast, FPS button disappear.

I'm a casual WoW boxer and have just started using this recently so forgive my naivety. During certain scenarios, warfronts for instance, the buttons mentioned in the subject will disappear and my keymaps on that character will stop working. I have to exit the game with that character and log back in to fix it. Reload of UI does not fix it. Unsure what to do. Any help would be greatly appreciated.

That was fixed in build 6305.
If you don't have this or greater, then you need to let InnerSpace update.
