To see cancelled bookings navigate to BookingsCancellations tab. 


There you can filter cancellations by modification dates, stay or check-in and check-out dates. You can open such a reservation as regular bookings to check its details (with double click or option to edit reservation under right click menu).


Cancelled Bookings are not displayed in the Daily View tab, nor in Bed View in any of the sections, but you can always find them through the search bar.
