I'm running the latest version of Telerik Controls and am hooking up a RadFilter to a RadGrid. When I have a GridCalculatedColumn set up as "Filterable" on my grid, the RadFilter displays duplicate items for that column. When I turn off filtering for that column, it removes both items from the filter. I've attached an image as an example.
"Tarpon Get %"
Is this a bug in the RadFilter? Or is there a way of preventing this duplication while still being able to filter on those columns?
