After Clarity upgrade from version 16.1.3 to 16.2.3 the order of the investments is shown in a different order on My Timesheets.
Before 16.2.3 projects showed at the top of of the list (in alphabetical order and tasks in alphabetical order)
In 16.2.3 now CITs show at the top followed by Projects and lastly Ideas.
In each section the investments and tasks do sort on their IDs.
This issue has been reported to our internal Engineering Team via DE155844.
Workaround: Viewing the Timesheet from the Details Tab the tasks are sorted Alphabetically
Note: Issue has been resolved:
Fixed In Build
16.3.1
