Unable to detonate Kelari´s Malediction

I had an interesting build in mind, and it just doesn't work and there should be no reason why. The main idea is to use the Skeletal Arsonist command ability to detonate the Beetles, I made sure that my Arsonist were able to target the minions. As of right now the advanced info on my Arsonist reads: Minion targeting Life threshold 770 that's on the command tab, on the Explosive Demise tab it reads 636. I don't know why that's different but either way my Beetles have 558 life and on top of that I use Sacrificial Lamb 2 on them which reads: Minions created By supported skills are always considered to be Detonable. I made sure that they are on in the skill panel and not excluded from targeting and for all of this to work I got the Unique Body Armour Vis Mortis and after all of this I find that I am unable to detonate my Beetles needless to say I'm really sad about my idea not working. I hope this is a Bug which can be resolved and if GGG doesn't want you to donate the Beetles than that should be stated on the skill, and you shouldn't be able to use Sacrificial Lamb on them

GGG pls fix this :(
