As a temporary workaround:
you can modify (for the A350-900) the file flight_model.cfg in ... Community\inibuilds-aircraft-a350\SimObjects\Airplanes\inibuilds\aircraft-a350-900 and change the first two lines in the [INTERACTIVE POINTS] section to e.g.
[INTERACTIVE POINTS]
number_of_interactive_points =13
interactive_point.0 =0.3,72.205162,-9.489041,1.653652,0,0,0,-75,90,4,85,3,-2,40
interactive_point.1 =0.3,72.205162,9.489041,1.653652,0,0,0,86,90,4,85,3,-2,33
