I have a double sliding door with a lock, that only works if I lift one side by about 1-2mm. This requieres a lot of force, since this is a solid wood door. The doors do not seem to be parallel to each other. Illustration:
The doors appears to be mounted in a way that makes adjustments rather hard. Do I have to unscrew the castors from the door and then remove them to try to adjust the distance? The doors are completely inside the door frame.
Edit: After the suggestion I tried to move/remove the stop element. It is loose after unscrewing it, but can't be moved or removed.
