Duplicate booking for the same time slot

Hi there,

I am really hoping you can help with this. We have one location set up, three workers and around 15 services. The plugin is being used for a piercing service.

We are getting loads of multiple bookings for the same time slot. Multiple locations is unchecked.

So eg. someone books in a new piercing with the piercer at 10:15.

It is also allowing someone to book a jewellery change with the same piercer at the same time slot.

It seems to book out the slots by service not by employee. It is causing massive issues especially with social distancing.

Please advise.
