How to set the default WingSpan and Range setting for the K14 GunSight

Until recently, when I started a mission with the P51D, the Gunsight was set at the lowest WingSpan setting and the shortest range on the K14.

Either I changed something without knowing how, or it was changed by default in a recent update...now when I start a new mission, by default the K14 is still set at the lowest wingspan setting, but at the farthest range setting.

How can I set the K14 up, so that it always defaults to the lowest Wingspan Setting and the Lowest Range Setting?...Is there a LUA file that can be edited?
