Is the problem fixed if you disable the "Pushback raise" option ?
This happened again yesterday with the pushback raise option disabled. PMDG Boeing 777-300ER at Aerosoft EGLL with the towbarless tug.

One thing I note when this happens is it seems to put the airplane into the air at the same elevation above the ground as the airport elevation. So in other words, if the airport elevation was 100 feet, it would put me 100 feet above the ground. If the airport elevation was 1,000 feet, it would put me 1,000 feet above the ground. Once again, this happens on the second leg of the flight.
