Dimension Field Captions on Dataports (v4)

Version 4 Problem : When a dimension field (say, Customer.Global Dimension 1 Code) is included as a filter on a report the system correctly shows the Code Caption (set on the dimension table, e.g. department code) on the dialog window, rather than “Global Dimension 1 Code”. However, when the same dimension field is included as a filter on a dataport the system shows “Global Dimension 1 Code”. Is this a known feature or have I failed to change a setting somewhere?

Apparently, it’s a bug (not sure if it’s known, though, or reported, for that matter).
