Problem with activating licence

We bought licences for our Backup Exec 12.5 . We use Exec on one server and two remote agents. So we bougt 3 licences, one for Exec and two for agents. Activating of Backup Exec was ok. Problem is with agents. On  PDF certificate is this  SYMC BACKUP EXEC AGENT FOR WINDOWS SYSTEMS 12.5 WIN PER SERVER BNDL STD LIC GOV BAND S ESSENTIAL 12MO  License Key(s): xx-xxxxx-xxxxx   Quantity : 2   I used activating key and it activated only one agent. There is only one license key and it isnt acting as two licences, but quantity is 2. I cant use it twice. Licence Assesment tool shows 1/2 agent licences activated so im missing one license. But we bought two. Are we missing one licence key on pdf certificate?

Thanks for any help.
