Spells: Malo line overwriting Bobbing corpse, and DMF (?)

[vouss]

Are the mage and shaman malo lines supposed to be overwriting bobbing corpse? And can any necromancers confirm/deny that it's overwriting their DMF?

AND, if it is supposed to be overwriting them, should it be moving to the bottom slot, or occupying the slot BC/DMF were in? Currently its' overwriting the slot my bobbing corpse is in, then if I zone or camp out / in it moves to my top slot. That seems wrong.
