GUP server name conflict

Hi All,

I have changed the GUP server name from AAA to BBB and IP address is not changed.
I have found both the records AAA and BBB in the console.Issue is the old record AAA is still showing as GUP and new record is not showing as GUP.
I have not done any changes apart from GUP server renaming.
 

My requirement is, Group Update Provider should be TRUE for BBB record.
Please let us know how to do.
