Issues adding GlobalSign SSL

I have purchased a DV SSL certificate from GlobalSign. The common name is mydomain.kom, and it covers the www version too.

When I add the CSR and certificate to Cyber Panel, it adds okay.

But then when I visit www.mywebsite.kom the cert is invalid. And when I look at the certificate, it shows common name as mail.www.mydomain.kom

Where the common name on the actual cert is mydomain.kom
