Ikea Besta Vara door does not fit

Good morning. I am despairing. I have been trying for 2 hours to adjust the cabinet doors of the Besta shelf. Each shelf door fits perfectly in height and closes flush on its own. However, you can see in the photos that the doors do not fit together. They actually need to be 5mm further out each. But that is no longer possible. The screws are almost completely loosened. When I hold the cabinet doors in place, they fit, though. Is the hinge defective now?

Damn, how can I insert photos from the phone?
