For me, this is the one annoyance about the XTR display. Low and high are natural opposite. Top and Bottom are naturally opposites. Low and top are an odd mix to choose, but I guess it was chosen by a Japanese person. It's certainly not a problem, but it's not ideal IMO.
With integrated axle cranksets, there is not much you can do about chainline; the only option is to move spacers from one end of the axle to the other, but often there are no spacers so you have no options.
