Get the bone you hit returns none?

I’m not sure what I"m missing here. On my projectiles hit event the bone hit returns none on the character I hit. It is hitting the players mesh but returning none for the bone?

In the first screenshot you can see the blueprint for my projectile, and it’s collision settings. The collision sphere is the root node of this blueprint. This blueprint prints out that I did in fact hit the characters mesh but that I got none for the bone.

In the second screenshot you can see my collision settings for the skeletal mesh of the character.

In the third screenshot you can see I set the skeletal mesh to per poly collision, with the physics asset.

In the game it behaves as expected. It hits and is blocked by the characters mesh, but I can’t get which bone it hit. Am I missing something here? Any help is greatly appreciated. Thank you!
