All products that have the product option Bookings / Reservations assigned will display these links when displaying all the listings.
A booking cannot be moved to another free slot to preserve double booking integrity and preserve over subscription of booking slots. To move a booking slot to another free slot the initial slot / order will have to be deleted and then a new booking created to the new preferred time.
This ensures that data remains valid at all times and all online and offline orders are in perfect sync at all times.
Click the blue calendar link to edit bookings where you will be able to access the delete a booking link or alternatively you can view all orders and delete.
If already on the listing page the bookings links can be accessed as the diagram below.
