I'm currently using WooCommerce Bookings plugin on my wordpress site. The website is a wedding priest reservation/booking. Clients can book/reserve a priest for their wedding in which they can set a date and time.
The problem I'm currently having is that the time range of the priests are 8AM to 10AM, 10AM to 11AM, 11AM to 12PM, and so on. There should be a 1-hour buffer/delay time in between reservations/bookings so if 8AM to 10AM is reserved, 10AM to 11AM should not be available.
Reservation Availability Settings/Range
If I enable insert "1" into the "Require a buffer period of () hours between bookings" and disabling the "Adjacent Buffering" it removes 1 hour globally.
See for example
