Orphaned dc entry in REPADMIN /SHOWVECTOR /LATENCY

Hi everyone, 

scenario: total 4 DomainController one of these RODC. The three writeable DCs are on the mainsite (default-first-site) and the rodc located on remote site. One year ago there was a dc crasch and one dc was uninstalled and installed again. Before metadatacleanup was done (after crash). DCs name is the same as before crash. No replication issues after the installation. 

Here is my question: after integrating the "new dc" I detected after executing this command

repadmin /showvector /latency "CN=schema,dc=domain,dc=de"

that DSA is set to "deleted DSA"

I found these Links, so everything was fine.

Event ID 1864 occured serveral times and half a year later it disappeared. Great!

After executing the same command again I see 3 DCs alive and one orphand. 

If I use PowerShell see the Output: 

Get-ADReplicationUpToDatenessVectorTable -Target dc01 | fl

Is it possible to remove the cursive entry (no PartnerInvocationID)? If it is possible how and where can I remove it? I searched in ADSI but found nothing. Sites and Services also no match. 

Thanks for your advice.
