My recommendation would be to reset to default any customization for that aircraft. After the update, even though I do not have any heavy customization, except for the 'Not to open the Fuel Page', the catering guys were walking through the left doors, before I had a chance to open them. When they were done, GSX was waiting for me to close the doors, when in fact they were not open. Reset the file worked for me.
Best of luck!
