If you are seeing default aircraft generated at gates with FS Traffic installed and enabled, this suggests that your MSFS ‘Traffic’ settings may not be set per our recommended settings. The MSFS ‘Traffic’ settings can be found at MSFS Options > General Options > Traffic and we recommend the following:
AIRCRAFT TRAFFIC TYPE – OFF. This will ensure that MSFS doesn’t attempt to generate any of its own default AI Traffic
GROUND AIRCRAFT DENSITY – 0. This will ensure that no static default MSFS aircraft will be generated at the gates.
You may also see default MSFS aircraft generated through Multiplayer model matching.
