No Parking

I had the strange taxi for take off when I clicked on taxi to parking or gate. I was in a 767 landing at KDFW. I'm using simflyers scenery with parking at every gate. So there's over 100 gate parking and a large amount of cargo parking. I had thought that when it didn't let you select taxi to gate that all the gates were full. There was about 40 to 50 planes parked at the gates. So there was plenty of parking. Does MS have only 1 gate and 1 parking for each parking area available? So if it's being used it won't send you to another parking spot or gate? At KPDX where I live I have never had that problem and there are less spots available than I had at KDFW. Other times I've landed there it's sent me to a gate. I did check for broken taxi lines or not connected nodes. But all is well.John
