Backup Exec 2012 Trial Agent

Hi there,

Currently I'm facing issue with Backup Agent uninstallation. The Backup Exec 2012 all the while is working fine, until the day when I renew my Backup Exec 2012 license and I noticed that there's additional column indicating I'm using Trial version for few other agent like Linux agent. I never install that agent from the beginning and I didn't see there's any option for me to uninstall these agents.

Solution and advise from the expert are greatly appreciated.
