Where to check for a spacific Debug event

I am trying to figure out why whenever i shoot a zombie my game will freeze for a few seconds. i ran some tests and got the below results. According to this its caused by “Function//script/engine.actor.add component” and the tree above it designates that its my zombie character. But i do NOT have the add component node anywhere in the blueprinting for the Zombie character, or any of its casts. What else could it be talking about?
