Raketenautomat's sight doesnt work properly in arcade

The Raketenautomat’s sight doesnt work properly for me.
No penetrationindicator in 3rd person or gunnerview. No leadindicator on planes. when i adjust the sight for range it doesnt sho me to where i adjusted. i have to just the rough scale in the sight. The range adjustement problem also exists in realistic battles. Alternative sights doesnt give the standardsight option an ist always something something ush. The problems also exist in testdrive.
