Bug Description

Bug description

Persons queries on insights with a previous period show persons from both the current and previous period and repeat persons if they appear in both periods. Its not clear from the UI which is from which.

If you are on PostHog Cloud it would be really valuable if you can share any links where the problem occurs. This speeds up our ability to troubleshoot tremendously.

How to reproduce

1. Create an insight, with a current and previous period on unique users, in this case it was a stickiness report
   2.Click into the persons list
2. See users returned from both periods and potentially duplicate user records one from each period.
