Hi Wieger,

thank you for reaching out to us; I apologize for the later response, as we don't work on weekends.

Yes, this is the correct setting - please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. 

You can write credentials here just check Private Reply so nobody can see them except us.

Hello Wieger,

thank you so much for providing the information!

Here is the setting list that made this happen:

1. "Allow booking above maximum capacity" is enabled, so all appointments can be booked above maximum capacity, and all those above max capacity are added as "Pending" automatically - this overrides the "Approved" setting you made.

2. All employees except for "Summum Woman Utrecht" have minimum capacity and maximum capacity set to 5, for the "In Store" service (employee/Assigned services).

3. When you hover over each "Pending" appointment (customers section) in the Appointment section, you can see that all customers have green circles (approved), and there's no appointment (currently) that has 5 or more people added to the appointment. When 5 people book the same appointment, it will turn to "Approved", but my advice is to disable "Allow booking above maximum capacity" either way.
