Box collision not working as expected

Hey, I tried many things, by printing, the “isHolding” variable is set false. The Tag is set in every weapon blueprint. I noticed one thing, if I add a CollisionSphere to my SwordBP the collision is getting detected and its working perfectly. So I´m pretty sure the problem is here somehow.

Now you´re probably wondering why Im not just using the CollisionSphere when it´s working by using this, the problem is, as soon as I add the CollisionSphere, my SwordCollision stops working.
