Frozen Rows doen't work in 3rd subreport/sheet

[mitch_3]

Jasper 5.0.4

Master report with 3 sub reports, exporting to Excel, each SubReport is a different sheet.  I'm freezing the header rows using net.sf.jasperreports.export.xls.freeze.row.edge=Bottom on one of the column header objects.  One of the sub reports is the longest "detail" report, so I would normally want it to be the last sheet in the file.  If that sub report is the 3rd sub report, the rows are not frozen, but if I move it to be the 2nd sub report, then the frozen rows work properly.

Each sub report is in its own detail section.  Sub reports are separeted by a detail section with a single static text with net.sf.jasperreports.export.xls.break.after.row=true to force to a new sheet.

Any ideas how to make the frozen rows work on all sub reports?
