Export to Excel

Good afternoon

I am evaluating Aspose.Cell and I have problems creating subtotals in which I indicate that the subtotals are located at the top, it is doing badly.

Please could you tell me where the error is.
I attach the Excel file as well as the code I use.

        string dataDir = "";
        dataDir = @"C:\S102000\Temp\";
        Workbook workbook = new Workbook(dataDir + "2017.xlsx");

        Cells cells = workbook.Worksheets[0].Cells;

        CellArea ca = new CellArea();
        ca.StartRow = 1;
        ca.StartColumn = 0;
        ca.EndRow = 6553;
        ca.EndColumn = 52;

        cells.Subtotal(ca, 0, ConsolidationFunction.Sum, new int[] { 6, 7, 8, 9, 10, 11 }, false, false, false);

        workbook.Save(dataDir + "output.out.xlsx");

@ebarrera.s10peru,
