As part of Microsoft processes, some Microsoft license keys may not be stored or may be removed from the system after installation.  In some cases, the algorithm Microsoft uses to encode the license key may not be accessible to thir parties.  When Kaseya attempts to report the license key but does not find a key or cannot decrypt the algorithm, the Audit will reflect the license key as "BBBBB-BBBBB...".

This is a known issue caused by the restrictions placed on license recording by Microsoft.
