We see old timesheets from Closed periods shown in Modern UX, after we enabled it.
STEPS TO REPRODUCE
Expected Results: The Timesheet should not display in Modern UX as the time period is closed
Actual Results: The Timesheet does not display in Classic, but displays in Modern UX. Some customers have old timesheet data they were filtering out in this way and they find it displaying when they switch to Modern UX
Release : 15.9+

This was analyzed with Product Management through DE60677
This is working as designed. In 15.9.1 the Modern UX timesheets module was enhanced to allow users to filter so they can see the Timesheets within Closed Time Periods.
In Modern UX we have a field 'Time Period is Open' for which you can configure on the grid and filter out the Closed Time periods (Time Period is Open = Yes - to show only open periods).
When navigating on the timesheet carousel you can see the timesheets from Closed Time Periods along with their status. There is a banner on the timesheet itself informing the period is closed.
