How not to spawn new actors when they collide?

I did simple spawn in exact location in front of the character and i simply want not to spawn 2 objects one in another. I marked do not spawn when collides (image4) and the new objects does not care and spawns, doing what you can see
in the picture 3. My question is how to fix it or how to do it other way?

PS I tried also attaching triggerboxes to new objects, so if they would be overlapped they would destroy the new actor, with real effect of immediate destroying even if there were no collision. I placed triggerboxes on new and on existing actors with same result. I used also function “is overlapping actor” (without triggerbox) again with no effect. PS on image 5.

Please help.
