Why can't Geopak Zero out XS that don't have proposed?

As I do my earthwork runs, I have some construction that starts and stops and starts again. I would like Geopak to read those sections without proposed construction as "Zero volumes". Instead it skips over them, carrying earthwork quantities through areas that have no earthwork. This REALLY throws my numbers off and requires a fair amount of hand calculation to correct. I know about "Ignore Areas" or "Skip areas", but neither of them really works to give me zero areas when there is no construction. I can get correct results if I create a separate earthwork input file for each and every short run of construction, but this is time consuming and tedious. Why will Geopak not recognize areas of "zero" work?

19+50        0.0

20+00        5.6

20+50        0.0

21+00        2.3

21+50        4.9

22+00        0.0

How do I get Geopak to zero-out my cut/fill quantities when there is no construction at a given section?

Thank you.
