I do have ordered the clusters, not just moved things inside. BTW the clusters automaticaly display the right order when displayed vertically.
The question is : "Why 'Variant to Data' fills probe 19 wrong while probe 16 is right, even though the 'Pdt_D' cluster do mirror the column ordering ?"
Simple question calls for simple answer.
Check the tab order of the cluster before probe 19. It's the tab order that decides the order out of the elements.
