1. Find the no-show reservation and click 'Edit' in top right corner.
2. Go to the room with no-show status and press the revert-icon after the status.
If the check-out date for the reservation is already passed the reservation will become 'Checked out'.
If it is before the reservation should have checked out the reservation will become 'Confirmed' and you can make changes to it or check in from the Arrival list for the original arrival date.
If the reservation is not checked-in it will become no-show again next night.
