When 40 subreports are added programmatically to a report the last subreport to be added is shown first while all other reports are in the correct order

Question

I am loading multiple sub-reports (up to 40) into a master report document using the Crystal SDK. This is accomplished by obtaining a reference to the detail area, adding a section to it, and then importing the subreport into the detail area. The master report does not contain a whereclause and contains no data other than the other sections so it is display only once.
When I add the section to the master report I give an index of -1 so that it would always appear on the bottom in the report. This works until I print a report containing exactly 40 reports at which time the last section is shown at the top of the report. All other sections (and hence subreports) appear in the correct order. If I print less than 40 reports all sections are in the correct order. If I print more, the export process crashes as documented in Invalid Section Height when I load the nth subreport
I am using Crystal Reports SDK 13.0.8. Visual Studio 2012. .NET 4.5.2.
The pertinent bit of code is shown below. What might I be doing incorrectly? Is this a Crystal SDK bug?
Thanks,
Ryan
private ReportDocument AddSubReportToParent(string subReportName, string fileName)
    try
        CrystalDecisions.ReportAppServer.ReportDefModel.ISCRArea headerArea = _crystalDocument.ReportClientDocument.ReportDefController.ReportDefinition.ReportHeaderArea;
        CrystalDecisions.ReportAppServer.ReportDefModel.ISCRArea detailArea = _crystalDocument.ReportClientDocument.ReportDefController.ReportDefinition.DetailArea;
        CrystalDecisions.ReportAppServer.ReportDefModel.ISCRArea footerArea = _crystalDocument.ReportClientDocument.ReportDefController.ReportDefinition.ReportFooterArea;
        CrystalDecisions.ReportAppServer.ReportDefModel.Section section = new CrystalDecisions.ReportAppServer.ReportDefModel.Section();
        // strip dots from name (any character that is not a number or letter causes a name/ID runtime error from the Crystal Reports SDK)
        string sectionName = "Section" + subReportName.Replace(".", "");
        section.Name = sectionName;
        section.Kind = CrystalDecisions.ReportAppServer.ReportDefModel.CrAreaSectionKindEnum.crAreaSectionKindDetail;
        section.Width = headerArea.Sections[0].Width;
       _crystalDocument.ReportClientDocument.ReportDefController.ReportSectionController.Add(section, detailArea, -1);
        _crystalDocument.ReportClientDocument.SubreportController.ImportSubreport(subReportName, _configSettings.InputPath + "\\" + fileName, section);
        ReportDocument subreport = _crystalDocument.OpenSubreport(subReportName);
        return subreport;
    catch (Exception ex)
        Logger.ErrorException(ex);
        throw;
