Agent for Windows licensing issues

Hi,

I am running backup exec 2012 and I am having an issue where the licensing is being incorrectly reported by the Symantec Backup Exec License Assessment Tool Report. It has listed one of the servers 4 times under the Agent for Windows and which gives me a does not meet licensing requirements error:

Agent for Windows               N/A            7               8                  No, need 1 licenses

Which is not correct as one of the servers is listed 4 times under the Server/Device name. 

Where can I look to try and rectify this?
