Essence - Einhar bug

I am using the following for the essence mobs:

1. idol with "of essences" mod; imprisoned monsters in your maps have at least 1 essence at the highest possible tier
2. Essence Scarab of Ascent
3 Essence Scarab of Calcification
4. white conqueror map t 15

It seems that when an Einhar mob would spawn, they get turned into an essence mob with the Calcification scarab but without one of the #1 and #2 of the modifiers above affecting them.
