When saving an order that has been calculated, if the order had errors when calculating, display a warning message that says the order is still un-valid before saving it.
When modifying an order, if the chosen blanks are changed via the “F6/Blanks” screen, you could save the order as valid without re-calculating it. This would cause issues on the devices. The order modify screen has been changed to request a re-calculation of the job before allowing it to be saved when the selected blanks are changed.
