Camera Collision doesnt collide / forces camera ot

I have placed a Camera Collision volume like this:

before I move the camera it correctly views from top down: (red is where the blocking volume is)

when I move the camera further to the left into to the camera collision volume, it doesn’t collide but it just forces the camera into the ground and I’m able to pass through it:
