You will need to remove the duplicate certificate first by running the following command in the Exchange Managenent Shell:

Remove-ExchangeCertificate -thumbprint <thumbprint>

When you completed the pending request did is say it was a success?

If so close and re-open the Exchange Console.  Any change?

Can you right click and select Assign Services?
