This menu gives an idea of loading and available rooms. You can see how many rooms are available on a given date, as well as resales. If there is a resale, then this block will look like this.
Positive numbers indicate the number of available seats in this category. If the number is negative, the number of bookings exceeds the availability.
To find out why the transfer happened, right-click on the block with a negative value and select Availability change history.
A window will appear showing at what point and why the transfer occurred.
