Discovered another issue, when you got static Ground Aircraft turned on you got Airliners spawning at small airfields where they are not suppose to be. I removed this addon and it stopped, i installed the addon again and poof there they were again. No idea why it happens but it does. Examples they spawned at PAKW and PAKT in Canada both in Alaska. Tried it with the addon airports that i have and without both ended with the same result. It's definitely this addon Simple Traffic that is causing it because when its uninstalled it never happens and soon as you install it again poof there they are.
