The range circles appear off because you have "Draw units at altitude" turned on in Game Options | Map Display. This option draws planes at varying altitudes with a line to the ground (with the length of the line increasing with altitude). So the plane icon is not drawn at ground level coordinates but the range circles are drawn at ground level coordinates. I, personally, don't use the draw units at altitude for this exact reason.

Thanks MauriceB! New to CMO and I didn't realize this setting caused the offset!
For the dev's, I've debugged the issue and found the root cause. If I plot a course on any of the flights, this issue occurs. Not sure why, but I retried the tutorial scenario without plotting any courses for any of the flights and it passed without the error. HTH others.
