BehaviorTree: How to create a single task for playing different anim montages for different skeletons?

Hi, i have two blueprints (BP_Monster, BP_Zombie) and two behaviortrees (BT_Monster, BT_Zombie). I created a single task for playing a specific anim montage. I want to use this task in different behaviortrees with different skeletons and different anim montages. It works for one BP_Monster and one BP_Zombie at the same time in the world, but if there are two BP_Monsters or two BP_Zombie only one of them execute the anim montage.



Sure, i know why this doesnt working for several BP_Monster/BP_Zombies but i have no idea how to fix this problem. Any ideas?
