Is Read-Only the Problem with my Blueprint?

Hello. I’m having an issue with making a keycard opening a door. I followed Ben Ormstad’s tutorial on youtube and adjusted it for a door in a separate project and everything worked. However, I migrated the blueprints shown here to the actual project and everytime I enter the door even with the keycard, the string reads: Access Denied, Need Keycard. I have tried everything from remaking the blueprints, migrating, checking the blueprints but nothing seems to fix the problem. The only difference I can find is that the Interface blueprint is Read Only. I’m still a student and learning on my own but I know it works in the original project I made it in so I don’t understand why the migrated version doesn’t work either. Side by side, everything looks the same. In game, they are not.

The first three images are from the blueprints migrated. The last image is the Interface in the original project. Thank you for your help in advance.
