Errors in row numbering in both [Customfield : Rownumber] and [Global : View result counter]

Howdy,

When using Views Calc table both of my row numbering options go haywire. The [Global] "View Result Counter" turns into nothing but "1" (where previously it was a working counter) and the [Customfield] "Rownumber" is incremented by the number of results on the page. Meaning if I have 25 results on a page, the first row on that page is "26."

No clue as to how to diagnose beyond this. But both of the above variables work fine with standard Views table.
