Hi   I really enjoy the plugin but I cannot overcome the issue of overbooking. In my test environment I have -2 services to choose from -2 locations to choose from -1 worker (I dont book per worker, so it is not relevant, basically the worker)     In service configuration I put in 10 minutes duration, 10 minutes slot step, because I have 6 slots every hour. No need to block before or after. My goal is to use this tool to be able to book visits for my patients. However a visitor should not be able to book a visit at 12:00 (lasting 10 minutes) if anyone else has already booked ANY service AT THIS particular location during THIS PARTICULAR time slot.   I honestly tried everything.. Multiple work on and off etc.. I even tried making 1 worker, 1 service and 1 location... and it still allows me to book 2 separate visits on the same time. I really hope, you can help me with this issue, because apart from that, the plugin works amazingly and is exactly the tool I need.   Regards
