Select the door in the schedule and then use the buttons at the top to select and show in 2D or 3D.
You should then be able to delete or modify the door.
Or just set your schedule criteria to not include doors with an ID of "FEIL".
This doesn't help you find and fix the problem but it won't show in the schedule.
