I am trying to get Top/bottom rank reporting for groups working in 7.1.9 but it dosn't seem to be working.  Has anyone used this before? I am wondering if I am configuring it wrong.

E.g. I am testing with a simple report that returns instances of a particular class and have configured to return the top ranked 5 rows for each group based on created date:

Reading the help the grouping is based on the "group results" check box.

So I have set this on the Report Viewer tab.

Before checking:

After checking:

But when i run the report i still get more than 5 rows for the group (38 rows).  I was expecting only to see the top 5 for this Admin operator (as highlighted).  If i switch to using Top ranking for OverAll report then it works.
