Opscenter showing different policies than master server

Hello,

I am having an issue where Opscenter is showing different policies than what is on our master server. The policies it shows no longer exist and have been removed from the master server.  This is causing opscenter to send 24 hour failure reports. The current version being run is 7.6.0.2

Has anyone come across an issue like this before? Is there a way to re-sync the policy or remove the clients from the policy in opscenter?
