We've just launched a few feature called Notifications. You will find it in the top right hand navigation of the BTA admin.
This feature will allow you to see orders that come in with an incomplete booking. (Incomplete bookings typically occur because of an error in set up or configuration).
When you receive a notification, click on it and enter the correct date in the booking and hit save.
If you need help troubleshooting the reason for the incomplete booking please contact firstname.lastname@example.org.
