Bug with outgoing healing on warlocks

daria

When you slot companions with outgoing healing bonuses you get a negative percentage on your character chart. For a blue companion, you get a 1.8% outgoing healing bonus and - 0.2% outgoing healing at the same time. On Cleric and Paladin, you get the same 1.8% outgoing healing bonus but you also get + 0.2% outgoing healing at the same time.
Sorry, I don't know if what I'm saying is clear or not.
