Availability issues for a bookable product in woocommerce

I had an accommodation product on woocommerce and was having issues with the availability that it was calculating, so i changed it to a bookable product.
I’ve now figured out that with the accommodation product the availability wasn’t calculating correctly as bookings from the check in day were then being counted on the following day (check out day) as the check out time was for the morning of the following day. (hope that makes sense)

eg – check in friday 10th september
check out saturday 11th september

The check out time means that booking is showing up on the 11th september, but as a result is also taking up availability for that day, when in reality they are checking out in the morning so the room is still available for another check in on the same day.

Since changing over to a bookable product I am not having this problem however any bookings that are in the system that were made when it was an accommodation product are still blocking the availability.

Please help!
