Machines are cranky
i was there last week and came to the airport at 8:30pm for the 00:30 flight to dfw. I needed the boarding passes to get to the lounge. The machines are cranky to say the least. Some of them have dead pixels/areas so the submit button on some screens did not respond or the passport scanner would not scan my passport. I ended up using the manual option of entering my info from passport and was able to get boarding passes.
