I have just downloaded the SR20 G1000 and seem to be experiencing a bug - or I am missing something. When starting a flight, my plane is completely empty of fuel. When I try to add fuel through the "Load Manager" tab under the "Cirrus SR20 G1000" menu, it does not allow me to change the sliders away from zero to add fuel. Also if I try to change fuel levels through the default X-Plane 11 menu, it also doesn't work.
Any help would be appreciated, thanks!
