Missing client

Hello

I have install OpsCenter 7.5.0.5 (Build 20130209) some time ago and I thought that everything works well, but
today when I was creating a custom report and I wanted to select a specific client from the list of clients
(Create a custom report -> Select Parameters Tab, Filters -> Client -> Client Name -> Value)
i didn't found this client. Client is available in NetBackup.

Next I ran SQL Query
SELECT * FROM domain_client WHERE name="client_name"
the client was displayed with deleted status 0.

Do you know how to update/fix a client list in Opscenter?
Thanks
