The most common situation in this case is that you have a reservation with forwarding initiated, but it was canceled at a later time.
See an example below:
Reservation from March 15 to 18 canceled
Behavior on the listing calendar
The calendar is empty and available to get new reservations.
Behavior on the owner's calendar
The reservation remains on the owner's calendar as the forwarding amount has been confirmed.
If you work with manual reservation forwarding, remove the credit postings and move back to the forwarding status:
If you work with automatic reservation forwarding, you can inhibit the forwarding when reservations are canceled.
