Blueprint_Automated_Door_Tutorial - Door Frame doesn't block player

I worked through the tutorial here: A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums

Everything works fine, but my player can walk through the door frame. By comparison, the player cannot walk through the door. I’ve examined both objects and the settings seem to be identical.

Can someone explain the discrepancy?

Thanks
