When adding an Umbraco Radiobutton List data type to our category we're finding that we get the following error, presumably because the Select Value is being set to something other than one of the defined values. Falling back on DropDownList for the moment which appears to be working OK with the same settings but just wondering if there is some configuration we're missing to get the Radiobutton List to work. The same RadioButton list works fine within Umbraco, it's only within Ucommerce that we're seeing this issue.

[ArgumentOutOfRangeException: 'Icon' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value]
