Some flights missing

Specifically flights CCA17 and AIC1 are missing/incomplete. I only see one leg for both those flights when there should be multiple.

I see them in Flightradar 24 but not Flightaware. Known problem?

“Tracking data for this position-only flight is incomplete and potentially inaccurate.”

That means Flightaware does not have a flightplan to associate the flight with, it is just reporting ADS-B positions it’s seen.
