Hi, Thanks for the nice plugin. I like the features and it's fairly user-friendly. However, I'm struggling with the "Busy Slots" feature because slots aren't blocked after they have been put into a "confirmed" status.  I have the "Busy slots are calculated by same" field set to "Worker" and have also tried other options but it still won't block out a slot if it has already been booked. I tried changing a couple of settings with no luck. Any help will be great.
