Multipart Unrelated Data Set in Repeating Section

Hi,

I have an issue with Multipart Unrelated Data Set in Repeating Section.

I created a Data Model with two Data Sets that work with two different JDBC connections. Let's name them Data Set "A" and Data Set "B". Then I created a BI Publisher layout with single Repeatin Section. I putted a layout Grid inside that Repeating section and then putted the data from both Data Sets "A" and "B". I use a page break to separate list in repeating section.

When I run the report I can see information from both Data Sets "A" and "B" on the first list of Reapeating Section and I can see information from the only Data Set "A" in the second list of Repeating section. The same problem on the others lists of Repeating Section.
