Clients are listed under "available NVBU machines" instead of under "Clients" where there is only (4045158)

Title: Clients are listed under "available NVBU machines" instead of under "Clients" where there is only one entry called "<DEPRECATED - DO NOT USE>".
Date: Oct 10
Product & Version: NetVault All
OS Version: All
Module & Version: N/A
Application version: N/A


Symptoms:
Following changes to the client groups (removing / adding groups), clients cannot be added and all of the clients are listed under "available NVBU machines" instead of under "Clients", where there is only one entry called "<DEPRECATED - DO NOT USE>".
It looks the same in the clientlist.txt.
The clients can still be seen in the client groups.
But policies no longer show any members.
