I am using Booking to allow user book their class. Each hour will only allow 5 students. I have 5 staff accounts create to handle this. A clients book their time by themselves. However, when the client call me to ask me to cancel his appointment, 5 of them in the same time slot are being deleted at the same time. Even though I select this client to delete. This time slot has become available..... not sure what's wrong. Is something I setup incorrectly? Thanks for your help!
