    Can you share the aircraft ICAO hex codes and registrations? Are they ADS-B equipped?

    There might be no coverage at low level where you fly them.

    Why not get your own ADS-B receiver?

    They likely aren't blocked. There is clearly bad signal (or mlat only on some) on playback.

    Solution. Build a receiver nearby.

    If you have your own receiver you can also check what the local receiver gets.
    (Local webinterface)

    That would for example show you if the ADS-B is not working correctly.

    (Maybe they are not transmitting position thus requiring MLAT, that may explain the broken tracks in the history)

    Thank you all the problem has been solved.
    The configurations for the transponder has been reset on one of these aircraft ( A7-PPP) and now we can see it flying.
    I appreciate all your help.
