What's missing from your report is where your airplane was parked.
There's also a minimum distance for the departing parking spot to be chosen (so they won't pop-up in front of you) so, if you set up only one vehicle parking, and you happen to call GSX when you are parked too close to it, they will depart from another random parking.
What's sure, instead, they will NEVER depart "between" to parking spots, as in your report so, it's possible you are editing a file but GSX is using another one.
