I'm having the same issue as the OP, and it's frankly quite annoying.
I've noticed this as well.
Is there anything that can be done to 'fix' this, or do we need to wait untill a new release/Blizzard update?
It's a problem with the Unitbuff() function built into the blizzard UI. It's returning buffs that are castable, instead of buffs that are castable by you. It will require a patch to fix, it's not an AG or Pitbull issue.
Noticed last night that my buffs were no longer being filtered. Auras were, but it seemed that anything that was a buff castable by any class (including fel armor, priest, druid, mage buffs, etc) were visible on my paladin.
