Pax IKEA cabinet system/Lyngdal cabinet doors, front door is scraping

For a few days now, the front of the two doors has been dragging. The rear one still slides perfectly. After inspection, to my knowledge, I could not see that the door is not running in the correct guides at the top and bottom. Does anyone have a tip on where I should look for the error?

Still sounds like the door has jumped out of the track.
