Duplicate actor with spline in it.

Hi,

I’m having this problem and i don’t know why.
I have an actor with a spline and a mesh in it. I’ve made a blueprint so that I can climb on. The blueprint works when I only have one actor of this out on the map.
But when I duplicate the actor and try to climb, it jumps over to the other actor when overlapping. and vise versa when climbing on the other one.
I’m posting images of my script.
