QMSClient.SaveCALConfiguration doesn't seem to be working

Question

Can anyone help me understand why this below would not remove named cals. It seems to work fine until the very last line where it does the save. I don't get any exceptions or error messages.

When i look in QV Management console under System>Licenses i still see the ones that were supposed to be removed (Named user CALs)

            }

        Console.WriteLine("\nDone");
        myCALs.NamedCALs.AssignedCALs = currentNamedCALs;
        Client.SaveCALConfiguration(myCALs);
