This may help you as well as others here but I am notusing profit UI and I also have that same trouble, I don't use full default ui but I have several pieces. When I create a new character or share ui settings using the /load_uisettings command. I get stuck with channels I don't/can't use, can't join and can't leave. The channels I do want (have a few custom channels) disapear and are stuck with the same number...The one channel I always type /1 for has suddenly become /8 and no matter what I try I can't fix it! Also when I take off a level specific channel box then relog, I need to again remove that level checkmark again no matter which toon I use.
This has been driving me nuts for days. Im sure hoping someone has some idea of what it could be!
