I might have to go back through my tutorial for that part, because maybe I altered something, but I set it up like that, and I have the same issue. Master at 100%. others at something else… apply, quit come back, they are ok. Set master lower, save quit, come back in and all others were lowered down as well. Raise master and apply and quit come back in, master is right, but the other volumes do not go back up… argh.
