I tried going back a version, but the problem still exists, which may point to the simulator and not the SDK being the problem.
Also, unlike before when you selected a parking space to add a jet way, you don’t get the drop down below the parking space in the scenery editor to show the jet way belongs to the parking space. Though that could be because I have drawn most of the airport in ADE 1st.
I’m going to draw a test airport using the sdk only to see if that makes a difference.
