I'm sorry, but as you can see from the screenshot I attached, I cannot replicate the problem.
You said you reinstall P3D but, if you just uninstalled/reinstalled it, all your exiting preference would stay the same so, if the problem was caused by some kind of setting/tweak, it won't be solved by reinstalling. You would have to remove all the various preference folders of the sim:
%APPDATA%\Lockheed Martin\Prepar3d v4
%PROGRAMDATA%\Lockheed Martin\Prepar3d v4
%LOCALAPPDATA%\Lockheed Martin\Prepar3d v4
Then reinstall. That's the only true clean reinstall.
Of course, I assume you have updated KLAX to the current version, which can be done by running the FSDT Live Update when KLAX is installed.
