PMDG B777 and GSX

Whenever I attempt to use GSX with the T7 I get really frusterated because it will tell me to open the cargo door, and even if its open it will think is closed and keep saying "open cargo FWD and cargo AFT" it won't let me depart from the gate becase of this, and while catering, it says to open door 3, I open all of the doors and I still gets it wrong. I have installed latest GSX updates and patches.
