RPE Data Source Schema does not include the "Test Description" Section of the Test Case

I am trying to generate a document from RQM. It is a Test Case using the default test case template. In my RPE, I have generated the QM Data Source Schema, but there is no entry to the Test Case Description Section. When I put testcase/description in my RPE template, it pulls the Description field from the Summary Section from the Test Case.
Help...
