Unable to find overlapping actors

I’ve been following a youtube tutorial for a while now and for the most part everything has been working fine. My problem now is that when I attempt to use GetOverlappingActors, the array always returns a result of zero. I have double checked all my blueprints being used and ensured they all have Block All (I have also tried Overlap All) in their collision settings and they all have Generate Overlap Events enabled.

I’ve been searching around for a while now and can’t find the solution anywhere and unfortunately can’t really progress without this part working.
