When you are discussing "Single Object" I cannot see what you are pointing too. I am guessing it is the tabs at the top of the window. Also how did you get the map to show up in the drill down menu of Value for Shipment.
When you select the little black arrows on the Dashboard screen it will open up a new tab to display the drill down reports. Initially the tabs will be labeled "Single Object" and after the data fills into the report the tab label changes to report name such as Total Shipments or Country of Origin, etc. The map that displayed in the drill down from the Map of Shipments by Country of Origin has been removed from the drill down report so it no longer appears in this drill down.
