Hey
1. why do you have set "periodic calendars" in Global Configuration?
Im not quite sure. I was playing with different settings when I first configured the extension, and forgot to set it back.
2. why do you have set "Enable Maximum Reservation Limit"?
3. why do you have set "fix limit"?
These are rules set by the tennis club.
I changed all settings as per your instructions (although I was slightly unsure what you meant by "periodic calendars in global configuration". I assumed you meant "set everything to know under 'period calendar' in Booking configuration." maybe that's wrong though) but im still having the same problem. Included below are screen shots of the settings to make sure I understood you properly and another example screenshot.
