Character loses physics in a different level

Hello! I’m making a game in Paper2D and I’ve encountered a bizzare bug. When I run my game in the example map with the Paper Character that I’ve set up everything works fine. Whenever I try to test it on any other level it seems to fall through the Ledges (the default building meshes provided by Paper2D) even thought I haven’t changed anything related to collision. The coordinates seem to be fine as well. Any ideas on why this is happening?
