OnBeginOverlap does not get triggered by ThirdPersonCharacter

I’m new in working with unreal engine and i am desperately trying to get it working.

I placed a BoxCollision Actor in my World. Every time i run through it (ThirdPersonCharacter), it does not fire the OnBeginOverlap Event. But the moment my other Pawn (Enemy controlled by the AI) passes through it, it does fire normally. I don’t get why it doesn’t work as intended.

Trigger (BoxCollision Settings):

My ThirdPersonCharacter Components look like this:
TPC Components

and here are the collision settings of it:

My Enemy Pawn collision settings look like this:

Even though they look similar to me, there must be something different i just dont get.

Pls help :smiley:

Edit: Placing a second Collider inside the Capsule Component works as as workaround. Not the Fix i was looking for though.
