B89 Ball Bar Test Sphere error? (Spheres ID's mixed up?)

B89 Ball Bar Test Sphere error? (Spheres ID's mixed up?)

One of the last steps when performing a B89 Ball Bar test in DCC mode is, as the system prompts:

"Move the tip to the access position of Sphere 2, and press OK"

But then, the system starts measuring that Sphere, that I just determined as "Sphere 2", and indicates it's measuring the "Sphere 1" !

This confuses me as I would like to strictly follow the same order every time.

Any comments on this regard are welcome.

Please refer to to the approximate X,Y coordinates for spheres 1 and 2 vs. these coordinates when the system is measuring spheres 1 and 2 in DCC mode to (try to) clarify this confusing situation:
