Help me pls, I can't attack copied AIs with hit result under cursor

This is my blueprint, I’m using topdown template which actor will attack AI when I click right mouse button. I have many AI that I copied in viewport. Everything work almost fine but when I click between 2 enemies that are close to each other, my actor’s still attack 1st enemy. Sometime when another enemy pass by, my actor stop and attack it.
I don’t want to post much because my English is bad, but I’m pretty down this time. I could do everything you suggest.

Below he is freeze after I click enemies so many time (see print string), but when they are far away, everyting’s fine.


I found solution now, I made a sphere above my actor and shoot Line trace for object to hit actor under cursor. It’s work very good.
