Room remain booked after change status to cancel

Hello,

I have a problem with the Hotel Booking plugin,

After booking a room, I change the status in cancel, but the room does not become available again, it remains in the calendar as blocked even after deleting it.
It is a very big problem in using this module like this, the rooms remain blocked even if I cancel the reservation or it is not paid or deleted order.

How can I solve this problem?
I kept reading through the topics but I didn’t find a clear solution.

Thankyou!
