Hi Fabio and thank you for a great plugin. I'm just testing the free version before getting the premium version. Everything seems fine but the one big issue I have is that visitors are still able to book days and times that have already been booked and confirmed. This leeds to the posibility for a date and time to be booked multiple times.   Is there a way once a day and time is booked and confirmed it is no longer available on the calendar? Maybe I have missed something in the setup? Regards, Jeremy
