I've created a backup configuration and set up a rule so that it applies to a specific user and company. Most of my test client machines are picking up the appropriate backup plan but I have run into a few cases where a client machine does not pick up the backup plan. These clients are using the same user and password as the working clients but the plan does not appear. Applying the configuration from the MSP portal to the machine also does not work.

Any ideas on why this might be happening and how to fix it?

Thanks.
