Tracking myWHOLE flight (or past ones)

I just did a Lifeline Pilots flight today (CMF12R) and somewhere near YNG they gave me a new squawk (was 7234 changed to 5134). I got home, and decided to track CMF12R. It shows the last part of the flight after I got my new squawk code. I want to track the first part of the flight. It shows my activity log, as departing C03 - which is correct, but I can’t see my path for that flight.

How do I see the path for that particular flight, or any flight I may have taken that wasn’t my last one. I thought it used to be able to do this?
