Microsoft DPM 2010 MMC Crash

I switched a protected workstation from a server backup to a client backup.

Now when I go to the "Recovery" tab MMC crashes. If I remove the new protection group all works fine.

I did tell it to retain the old data. This may be (Hostname) listed below in the database. The new PG created was as hostname.domainname. Even after removing the PG this entry remains in the database listed below.

I found reference to multiple duplicate names in SQL and ran:

Select ServerName, Domainname from dbo.tbl_AM_Server

This returns the same results with the PG active and removed.

Hostname               |    Domainname
Hostname.domainname    |    Domainname

Is there a safe way to resolve this by removing the database entries?
