Q. I have an owner set up but they are not showing in the dropdown list when I search for owner bookings.
A. Owners who have not made an owner booking do not show up in the drop-down list when you search Owner Bookings > Booked by:
Only owners who have made booking bookings show up in that list. You can alternatively use the Owner's property to search by instead of the Owner's name by selecting Product instead of Booked by.
