I see a lot of third-party aircraft do not have very polished presentation inside the Aircraft Configuration screen. Cabin, Gear, Engine, Instrumentation and Additional Information are commonly blank, showing just -.
My understanding is these details inside the aircraft.cfg file in the various FLTSIM sections but I have only found the following keys ui_powerplant_specifics, ui_instrumentation and ui_additional_information. What are the required FLTSIM keys for Cabin and Gear? The MSFS SDK is quite unhelpful here and even the CFG Parameter Index is of no help.
