missing legs - IFR flight plan

Last night, I flew IOW > OTM > DSM > IOW on an IFR flight plan. When pulling up the track, why do I only see the last leg (DSM > IOW)? All legs before that (IOW > OTM >DSM) do not show.
???

What’s the tail number? Do the previous flights show in the activity log?

Currently, the map only shows the most recent flight.

N1351C
The flight was a continuous route that was filed from IOW > OTM > DSM > IOW with training approaches into OTM and DSM. Approaches were called as missed (no stops or touch and go’s) and proceeding on to the next point.
Is there a problem picking up all data from Chicago Center?
