Clean up the duplicate device elements in the NFA system and allow synchronization to complete between Data Sources in the CA Performance Management system.
If normal synchronization update cycles don't resolve the problem, some instances may require a full synchronization for the problem to resolve in CA Performance Center. In these situations be sure to check the box to request a Full Synchronization when requesting an on-demand synchronization of the NFA Data Source in the CA Performance Center Manage Data Sources page.
