Those objects are supposed to be animated!
In any case, thank to your report, I was able to find a bug in the Addon Manager, which doesn't sent the waypoints to animated objects created using its own functions (those controlled by the "Ground traffic" setting in the Addon Manager), which must have gone unnoticed, since our later sceneries use only Couatl/Python script for such functions, but older ones like LSGG or LSZH still do.
Run the FSDT Live Update now, when the sim is not running, to get the updated Addon Manager .DLL which will fix the problem.
Disabling the "Ground traffic" option in the Addon Manager, will remove such objects entirely.
