The problem of a too small menu entry has been discussed many times on the forum and, of course, it doesn't have anything to do with GSX.
It's an issue caused by some 3rd party airplanes, due to the unusual way their cockpit gauges are setup, which results in the sim being confused about the screen size, and reducing the Simconnect menu window so, after you load one of these airplanes, the Simconnect menu window will be too small to show all the required options. This, of course, affects each and every 3rd party application, not just GSX, since the Simconnect menu window is handled by the sim and the application don't have any kind of control over its size or positions.
Of course, the Simconnect menu window, can be resized with the mouse, to show the missing entries.
