splunk showing 1 event 2 times in multi site cluster

[pranay_adla]

We aren't supposed to see the same results from both sites. For a given event we should only see it coming from one site (whichever had the searchable copy). It almost appears that Splunk is giving a result from each site.

What might be the issue here and how to resolve

Are you sure the event wasn't ingested twice?

All of sudden all indexes in are have same issue but not all the events only few events showing duplicates.
Not an issue with ingestion twice
