Client Summary Dashboard in OPSCenter showing wrong NB version of clients

The clients could show up twice if a change occured, like an OS change/upgrade. Usuaully, I'll filter the dashboard report and exclude all clients that don't have any volume/job info in the right hand columns because chances are they are no longer in my environment.

Is that what you see when you see multiple entries for one client, where one has job info and the client with the older version has nothing.
