I have a few alts with same name diff faction and diff server,but when in menu i try to select one char to switch some addon on/off it selects as well diff char,diff faction,diff server but with same name as well.
Maybe forgot to say its outside game menu.
Blizz are you working on solution?

Bug is there from start. Menu cant differentiate two char same name on diff server. on top of it addon selection menu outside of game is bugged as well so selection of addons outside of game is totally diff then in game. I could select addon to turn off outside game and it would still be in game menu inside game even when i turned it off outside.
Bug report system that in now in place if f… as well. I finally reported bug in battle net app and still i am not sure if i did it in right place.
