Killing one enemy kills all enemies

Hi.
I am making several enemies to my player and I use a setup with - if collide with the bullet = remove.
my problem is that all similar enemies built from this same enemy also get killed. Is it not possible to use prefabs and copy enemies when you want them to die separately?

Thanks for all help in advance!

Show us your graph and how exactly it is “killing” (and spawning) the enemies. Likely you may not be destroying the object you think you are, or something in the flow is too eager.

I actually found the problem. I made a send node to the parent to be removed when hit by bullet. This send node killed all same enemies. But I stumbled into another problem! Hehe.
