Cannot get child colliders to overlap with world


I am making a fighting game, and have decided to use hurt/hit sphere colliders for my collision, that I parent to skeletal mesh sockets. The problem is currently I do not generate overlap events with the world, even with collision response set to all channels. I have been using 2.5 - Child Blueprints | Unreal Engine Documentation
for reference, but generate an error when i try to bind the parent event to a custom event on the child script. SetCollisionListener is called after I create the sphere collider blueprint and parent the sphere collider to the socket

Any help or work arounds for this (getting overlap with world for child colliders) would be greatly appreciated!
