Problem with spawning dynamic objects in volume box

Hi, I want to spawn meshes inside the volume box and it works fine when I simulate in the blueprint scene, but when I put the blueprint in the world, those spawning objects are not in the right place.

Spawning Actors is in world space (Location = ActorLocation + Offset)
Adding Components is in local Space (Location = Offset )

PS: It works there because in Bp viewport the default location is (0,0,0)

Thank you very much.
