opcenter report displaying old client name (VADP vmware backup)

another question, i may need to start another post. In the reports one of the clients name displays as a dash "-"

I cant seem to work out why. once again in vcentre it shows correctly and also in netbackup it shows correctly. i can't merge the - with the actual client name as - doesnt show up in the list. if i search the host alias's the client shows correctly but doesnt have a dash as an alias
