Incorrect/Missing Domain Controllers

Incorrect/Missing Domain Controllers

Hi, we have ADManager Plus (5.2.0) which is all up to date.  The problem I have is that we have many more domain controllers than I get in the computers, domain controllers report.  The computers that are missing from that report are in, just not showing up under domain controllers.
 
Any ideas?  Thanks.
