Health Logic Question for level I published "Fire Test"?

I'm trying to figure out the health logic between 3 different puppets. You can see them in the level i published called "Fire Test".

In the level the dragon shoots out fire, but only one of the puppets takes actual damage from the fire (the witch). The other puppet, an first person puppet, takes no damage.

I didn't make these puppets, but I've been tinkering around with them to try to get the first person puppet to also take fire damage, but I can't seem to get it to work.

Can someone take a look and see what I need to tweak?
