Formula incorrectly recalculates for large (>64K row) sheets

Using Aspose.Cells, V4.8.2.0. I have an Excel 2007 / XLSX book with large (150K or so row) sheet with a SUM formula, totaling all cells above in the applicable row (e.g. sum(M1:M150015)). When I load the sheet, I can see the proper value as a string value, however, if I invoke the CalculateFormula() method, the value is incorrectly calculated (see code and comments below). Looks like this may have to do with with the sheet having more than 64K rows, I have had no problems with smaller sheets before. See code below, should be easy to reproduce.


private static bool GetCostsFromFile(string strFilePath,
out decimal totalSales,
out decimal totalRebates)
{
double totalSales = 0;
double totalSales_NO_FORMULA = 0;

try
{
Aspose.Cells.License license = new Aspose.Cells.License();
license.SetLicense(“Aspose.Cells.lic”);

Aspose.Cells.Workbook wkb = new Workbook ();
wkb.Open(strFilePath);

Worksheet sheet = wkb.Worksheets[wkb.Worksheets.Count - 1];
int intRow = wkb.Worksheets[wkb.Worksheets.Count - 1].Cells.Rows.Count;
// ***** IF I TAKE NEXT STATEMENT OUT I GET THE RIGHT VALUE,
// BUT THEN I AM AT THE MERCY OF THE USER RECALCULATING
// FORMULAS BEFORE SAVING THE WORKSHEET
wkb.CalculateFormula(); // just in case
//
totalSales = (decimal) sheet.Cells[intRow -1, 12].DoubleValue;
totalSales_NO_FORMULA = (decimal) sheet.Cells[intRow-1, 13].DoubleValue;

return true;
}
catch (Exception ex)
{
Log.WriteLogEntry("Failed to get costs cost from : " + strFilePath);
return false;
}
