I have a problem with appointments/slots and any help would be highly appreciated. The problem is the following: Some slots show as used while in fact they are free! The slots that show as used are positioned : in between two regularly booked slots but also prior o after a regularly booked slot. No particular rule shows up I have done a few cheks: Pre-booking a slot seems ok Deleting a pre-booking frees up properly the slot. Confirmed booking works ok slot greyed up   Any suggestion/help would be appreciated Chiara
