bug/Scanning issue, for 2x2 Rubik's cube

[Safacan7]

Hi @dwalton76, I am trying to implement Herbert Kociemba's [Rubiks2x2x2-OptimalSolver] (https://github.com/hkociemba/Rubiks2x2x2-OptimalSolver) into my Mindstorms EV3 project. My robot is able to solve 3x3, however, when it comes to 2x2, it seems to be facing a scanning issue. I am confident that the RGB values captured are accurate with the calibration method. However, the cube printed out does not seem to match the actual cube.

I do not seem to figure out what is the problem, could it be the scanning order?

Here is the repository I am using for your reference:

Your help would be very much appreciated!
