Hello Aidan.

I honestly can't say what happened there. This didn't happen to me before, so I'll need to investigate.

Please provide me a temporary WP-admin (administrator) user 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 parties. 

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

Thank you Aidan.

This tends to happen when a user logs into the panel as an admin.

I can see that [email protected] is registered as both the Administrator and an employee in Amelia.

Can you ask the client to record the screen so we can see how this can be replicated, and then provide us with the login(s) for the users this is replicable with?

An Admin should never log in as the employee as that can cause issues like this. For example, if Neil was logged in as an admin, and then logged into the Employee Panel of Steve and approved an appointment, the conflict with the capabilities of roles can cause the appointment to go to another employee.
