'Build All in project' Errors in Flight_model.cfg

Hi

When I ‘Build All in project’

I get ‘Validation errors’

The details of the errors are ‘Unknown parameter’

Current culprits are (all within the flight_model.cfg and Engines.cfg):

within [CONTACT_POINTS]
water_longitudinal_friction_scalar =
water_lateral_friction_scalar =
water_steering_friction_scalar =

within [TURBOPROP_ENGINE]
InertialSeparatorOnTorque =

within [OBJ_AIRGEO_VTAIL.1]
position =
area =
span =
sweep =
dihedral =
incidence =

all of this section all of the parameters including the section heading
[OBJ_AIRGEO_HTAIL.0]
position =
area =
span =
sweep =
dihedral =
incidence =

within [AIRPLANE_GEOMETRY]
vtail_incidence = -3.5

Any suggestions? All of these are relatively new parameters.
thanks
Stu
