Hello Ralf

Your employee profile doesn't look correct to me. It should have a circle in the place of the profile image, so it could be some conflict here.

Also, the Google Calendar section can't be seen when you're creating a new employee. Once you create an employee, and save that employee, you need to re-enter his profile to log into Google Calendar.

If you're still having issues, 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.

Great news, Ralf

Thank you for letting me know.

If you have any further questions or issues, please feel free to open a new ticket, and we'll gladly help.
