Overlapping Actor Fails

Hey there,

I’ve been trying to make some spells in UE4, but I’ve run into a problem.
I’m making a flamethrower spell, and I’ve got a collision box for the area that’s supposed to be damaged.
But the overlapping of the actors results in a failure?

This is how I’ve got it set up: http://imgur.com/a/KXJ1w
The top post is the first part, where I set the enemy that’s overlapping the collision box.
(A little side note: The timer on the right (First picture) leads to the first node on the second picture, those 2 are connected.)

If someone could help me out on this, that’d be greatly appreciated!
