SSRS (BIDS) Map Distribution Range invalid by Paul Dioguardo

I have a map report created in VS BIDS 2008 R2 and published to SSRS 2008 R2. The map displays the counties (polygons) in Pennsylvania along with data resulting from a query. The map distribution is setup for equal distribution across 5 ranges. The ranges appear with overlapping values. There does not appear to be a way of forcing the ranges to not overlap. i.e, ranges appearing as 0-100, 100-200, 300-400 etc, should appear as 0-100, 101-200, 201-300, 301-400, etc. Having a range end value of one range match the start range value of the subsequent range is actually invalid. Even the examples in the MS SSRS on-line help documentation display the incorrectly overlapping ranges, but I can't find a way to force the ranges to not overlap while remaining dependent on a query result (and not a static custom-defined range)

The organization I work for is responsible for publishing correct data which is reviewed and used by researchers and governmental agencies. Publishing a map with overlapping distribution ranges is not acceptable.
