Desecrate Corpse Bug

I had 4 Corpses in my Hideout Desecrate Pool:

Carnage Chieftain
Perfect Warlord
Perfect Forest Warrior
Hulking Miscreation

I realized I only have 3 Spectres up, so I wanted to resummon them. I took my Raise Spectre Gem out and in again. Then I desecrated in my hideout, I got Carnage Chieftain, Perfect Forest Warrior and Perfect Warlord. Hulking Miscreation was missing, after a while only Carnage Chieftain was in my Desecrate Pool. I bought the Hulking Miscreation Corpse again and spawned it in my hideout, so I could summon it as my 4th Spectre. But when I use desecrate I still have only Carnage Chieftain. What is going on here?

Why is it that complicated to manage spectres, there is no information about my active spectres and I can't understand why I only have 1 Corpse in my Desecrate pool now?

I hope there is a solution for all of that, or else I wont get my spectres back when they die.
