The drone won't overlap or explode

I’ve tried to implement the Blueprint code from the “Getting Hurt” section of the FPS game. However, I cannot get the drones to overlap or to explode.

I can confirm that the drone is receiving no overlap signal from the Player after pressing F9 on the Overlap line and playing.

UPDATE:
I was able to fix this by replacing the explosion sphere collider.
