Your mistake is that you removed all the doors (except the door 2), which means NO GSX SERVICES will appear on the related doors. No wonder you say "it doesn't work", since you removed everything...
If your goal was to not have GSX waiting to open a door, you should not remove it. You should set it to "Door without open/close checks" in the editor, instead. This way, the door will still be there, just that GSX won't ask you to open or close it anymore.
Of course, this also means that, if you don't open a door, the catering crew and/or the baggage will start anyway and will appear to pass through the bulkheads. Which is precisely the reason why, by default, GSX WAITS for you to open a door, which is how the default configuration that comes with the plane is made.
