Starting with the out of the box RTC process template for SAFe, I created a new section in the details slot of the overview tab for a Program Epic. The new section is underneath the Detail section in the Details slot. When I create a new Program Epic work item in the web client, I see the new section  I created for it just as I expected.  However, when I try to create a Program Epic in the eclipse client, I only see the newly added section.  The details section is missing.   If I swap the order and put the new section above the Details section, then I see them correctly .in this new order in the web interface, but I only see the Details section in the eclipse client. 

It really doesn't matter what Process Template I start with or what work item.  The results are the same.
