Mathematical calculation of the true position (textual analysis)

Hello!
I hope and you can solve my doubts, in the image that I enclose is the evaluation of a real position, it is supposed that to calculate the position the deviations of the axes are taken, in this case X and Y (marked with red) the deviations that appear are very big deviations and do not correspond to the calculation of the position, doing the textual analysis takes the measured values of the row 2 of CONTS (row shaded in yellow), the values that correspond to the calculation of the position are those that are enclosed in the blue box and the same as the deviations.
My doubts are the following:
What are the CONTS values?
Why does the software take the values of the row that is in yellow and not the ones in the blue box?
How could I explain the calculation of the position by taking the values in the red box?
How is the DESV value calculated in textual analysis?

Thank you and success.
