Problem with generating collision

hi there,
I’m having problems generating collision for this asset I made,
as you can see in the included picture the collision is bridging the gap between the two outsticking pillars, because of this my character can’t walk past this section,
if somebody could help me that would be greatly appreciated.

You can easily select this box Collision and delete it.
Under Collision use “Add Simplified Box Collision” to create new Collision Boxes and align them to your pillars
