Uber elder challenge not recognized

My friend did uber uber elder (lvl 85 area) in shapers realm - challenge oppresive Opponents.

But i dont have the challenge.
I checked my atlas with voidstones, i have 3 voidstones there inserted, but on hover it says, that i need to kill defeat Maven and Elder in shapers realm, eventhough i have 3 voidstones already. Missing just Maven's.
