Configuration Integrity Check warning missing object (user) for component

[Helmut Schreiber]

The analysis of the configuration gives me two incomprehensible warnings related to project, component and user

• first warning: Missing object 715 objects refer to the missing user (no user name).
  • The recommendation is: Modify the objects to point to an existing user or remove the reference to the missing user.
• second warning: 7 objects refer to the missing user xxxxx, xxxxxx.
  
  • The recommendation is the same as above.

My question now is: how do I remove the reference to a user, which actually never was or is present: The default configuration is either "Project default" or "Unassigned".
