Hello Roshan

From your screenshots, I can see that the phone number is saved:

But the WP User says it can't find any data:

Your WP User needs to have the Amelia Employee user role in order to link to your existing Employee in Amelia. If you need to keep the current user role, you can install the User Role Editor plugin, and add another user role (Amelia Employee) to that user. After that, you will see that user in the drop-down.

Hi again Roshan

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.
