10g Reports issue with XML Data Source

Question

Hi,
Has anybody ever encountered an issue with Oracle 10g report using an XML as the data source? What happens is, some of the values in the XML are printed to the wrong column.
One of the elements in our XML file is a complex type with 10 elements under it. The first 5 are picked up properly, but the last 6 are not. Elements #6 to #9 has a minimum occurence of 0. What happens is when element #6 is present, but #7 is, the value for element #7 is passed on to element #6.
The XSD and XSL files are both valid since the reports were working when we were still using 9i. There is no hidden logic in the report which might cause this issue to come up, i.e., the report just picks up the values from the XML and prints it to the appropriate columns.
Any help will be greatly appreciated.
