Hiya,

This is regarding the 'Show Overdue Task' checkbox on calendar screen. 

When you enable "Show overdue tasks" in the calendar and navigate away from the calendar, and then navigate back to the calendar, Show overdue tasks is then disabled.

In versions prior to 2023 R1, Show overdue tasks, remained enabled when one navigated away from the calendar. 

The above has been fixed in 2026 R1. 

The only exception to above is: when you click on Task tab again the checkbox is unchecked which is intended behaviour (by design)

Hope this help!

Kind Regards,

Seema Singla
