Perfect Fiery Cannibal spectre not casting Purity of Fire

I have a Perfect Fiery Cannibal spectre, but it is not casting Purity of Fire.

It seems to be casting some small volcano spell, but not Purity of Fire like what is listed on the corpse.

I have the corpses that cast Purity of Ice and Purity of Lightning and they are working just fine, just the Perfect Fiery Cannibal is not casting their aura.

Yeah same here I cant seem to get it to cast Purity of Fire either.

I am having this issue as well.
