Navigation Question

So while practicing on my getting intercepts right and all by using the help with each tool, as I was doing this I couldnt help but notice, each one is upside down. What I mean by this is, if you turn the help on as you use the tools (protracter, waypoints etc.) you will see the degrees or directions and what not, but what Ive noticed is theyre all upside down, and at first I thought it was because Bearing was backwards from normal degrees (180 is actually North where as 0 and 360 degrees are almost always North) so then I checked by clicking on the waypoint plotter and noticed that South was in the position north was in and vice versa. I cant help but be annoyed by this as it kinda screws me up when I try to plot an intercept course coming to 90 degrees off track and what not. hope that makes sense
