Atttempting to include hours so as to allow multiple booking per day

WP 5.2.2
Booking Calendar Pro (Personal): 20.14

I have been using the free version for over a year. Now, however, we have people interested in booking multiple times per day
(we have options at 2 hrs, 2-4 hrs, and 5+ hrs)

However, I Enable Hours in the Theme Settings…
enable Multiple Hours
Min Hour count 2
Max hour count 12
Show Hours Availability enabled
click “Add Default Hours” and then delete the adds, so that single entries for 07:00 through 20:00 are listed
Set options to “Available” and (number available)=1
no price info.
no hour information info

but the booking page front end still shows “No Hour Available”
And the previous entries which I had in the free version (which have hours) don’t allow any additional bookings for those days.

How do I
1- keep my existing bookings
and
2- enable booking to be set by hour, now that I purchased the licensed version?
