It's not in the profile. Make sure Protected Items.xml in your base HB folder doesn't have the white items that aren't getting sold listed as items the bot is supposed to horde...which is just about every white object, haha.
EDIT: ForceMail.xml is there too, keeping you from selling stuff it is supposed to mail off...
Either way, I've never successfully had the bot sell everything I want it to....but emptying those two xml files might help somewhat. Otherwise, you have to resort to lootfilter I suppose...
