Outline.SummaryRowBelow isn't saved

Hi, Laurence!
SummaryRowBelow setting isn’t saved to the resulting file. For example:

// group some rows
excel.Worksheets[0].Outline.SummaryRowBelow = false;
excel.Worksheets[0].Cells.GroupRows(11, 12, true);
excel.Worksheets[0].Cells.GroupRows(14, 17, true);
excel.Worksheets[0].Cells.GroupRows(10, 18, true);

// save file
excel.Save(“sample.xls”, FileFormatType.Default);

Saved file has SummaryRowBelow option set to true.

Bugs in grouping rows are fixed.

Hi Laurence,
