Cleaning up DC errors

Hello. Our AD Domain is running Windows 2008 R2 at the Forest and Functional level.  Our primary DC's containing the FSMO rules live on the 2008 R2 servers.  We have Windows 2016 DC's in the mix and are preparing to move the FSMO roles to the Windows 2016 servers.

So, in DCDiag, I have 2 servers I cannot get rid of.  Combed through all of DNS in Windows and Bind (We have both), not there, Checked AD, not there, Ran through with powershell to look at inactive systems.. these are not in the list.  How do I get rid of these entries to clean this up?
