Manual disc eject not working - no screw found underneath bottom O tag

Strange issue with a disc not ejecting - tried to manual eject the disc on my PS4 Pro like I did a while ago, but this time I could not feel any screw underneath the removable tag like you normally would. I only feel some kind of sheet. When pressed a little harder I seemed to have pushed through this sheet, but afraid to do anything else. PS4 still works fine for the rest. Anyone any clues why the manual eject screw seems to have disapeared, and how to fix? Thanks
