Chaos collision events only seem to generate against self

I’m trying to play sounds whenever my pieces broken by chaos hit other things.

Both Component and Other Component are printing as the same thing: the GeometryCollectionComponent inside the blueprint. I’ve tried turning on “simulation generates hit events” in other objects, but it doesn’t seem to work. The only plausible theory I have for collisions against itself is one piece hitting another, but either way, I’m not sure why they wouldn’t be triggering against other objects.

Has anyone run into this?
