Bug in mixture setting or not?

[PotNoodles]

If you look in the cockpit of the Hurricane you can just make out some writing near the mixture lever saying rich & weak. When the lever is pushed forwards it is right where it says weak, but the mixture is actually rich according to the mini display on your screen. On the mini display I take it that rich is when the gauge is at the top on the mini display, is this correct? This is no big problem but I am just wondering if this is normal.
