Your screenshot seems to show two jetways on the same spot, as if the static one wasn't removed when the dynamic started. This can also possibly be caused by Simconnect being overflown with so many commands from other addons (like weather engines, for example), that GSX couldn't get enough time to ask the sim to remove the static jetway, because the sim was too busy accepting commands from other addons.
See if it happens with a default airplane.
