SpawnActor Arrows overlapping

Encountered some issues with the spawning arrows.Using the template from the endless runner videos to spawn a floor. The issue comes when I try to add arrows to accomodate the x and y axis for a more dimensional floor generation. My goal is to have a graphed algorithm for a level generator (my attempt at a roguelike) but I’m having issues with the floor tile overlapping each other. I think that a trigger event could be used but not used to the branching graphs so was wondering if there was maybe a more clearcut programming solution?
