The airport is made correctly, with its gates properly assigned, with their proper radius and properties according to real life, and it would be wrong to add wrong data in the scenery, just to sidestep what is clearly a bug in the sim that can be corrected at any time, considering the simulator is under heavy development.
So, be sure you file this bug to MS support using Zendesk, and if enough of you will do the same, you'll increase the chances for the bug to be fixed.
I have absolutely no doubt that your scenery is made correctly and I did not criticize the product in my message.
You think it is wrong to be flexible and improve something, even at the cost of doing something that is not fully academic and maybe even temporarily. OK, fine I note it.
Now, speaking of the FS bug I found, I don't need you to tell me what to do.
Have a nice day.
