Duplicate labels in ArcGIS ServerREST map service when viewing through OpenLayers API

I've created a very simple ArcGIS Server dynamic map service for a single polygon feature in an MXD. Labels are turned on for the layer with the setting "remove duplicate labels" (Placement Tab of the Placement Properties of Labels Tab). When I view the service in my OpenLayers demo app, the labels are duplicating. See attachment. Any idea how to prevent this label duplication? I only want one label per feature.

Relevant code snippet:

RBlabels= new OpenLayers.Layer.ArcGIS93Rest("RWQCBs with labels",
                    {layers: "show:0",
                    format: "PNG24",
                    transparent: "true"},
                    {isBaseLayer: false});
