Match up parameters between qgroundcontrol and ardusub

When I start up with ArduSub on the pixhawk and QGroundControl running on my laptop QGroundControl says that it can’t get all the parameters from ArduSub.

Where does QGroundControl get it’s list of parameters it wants and where does ardusub have its list?

I’d like to match them up. Also, how can I find out shich ones QGroundControl is complaining about?

Thanks
