When attempting to Insert a new field at index 0 on XamDataGrid.FieldLayout.First().Fields, it consistently appears visually in the second column, despite it properly being assigned the 0^th index.  In fact, .Fields.Insert(0, field) visually appears exactly the same as .Fields.Insert(1, field)

I am attempting to insert a new column to certain XamDataGrids via a DependencyProperty, which when set to True, calls an XamDataGrid_Loaded() event:

        static void xamDataGrid_Loaded(object sender, RoutedEventArgs e)

        {

            var grid = sender as XamDataGrid;

            var field = new UnboundField

            {

                Name = "MaxAlertSeverity",

                Label = string.Empty,

                Width = FieldLength.Auto,

                Settings = new FieldSettings()

                {

                    CellValuePresenterStyle = Application.Current.Resources["AlertIndicatorCellValuePresenter"] as Style,

                    AllowSummaries = false,

                    AllowRecordFiltering = false,

                    AllowFixing = AllowFieldFixing.No

                }

            };

            var fieldLayout = grid.FieldLayouts.First();

            var bkn = fieldLayout.Fields.Where(f => f.Name == "BKN").First();

            var bknPos = fieldLayout.Fields.IndexOf(bkn);

            if (bknPos > 0)

                fieldLayout.Fields.Insert(bknPos, field);

            else

            {

                // weird hack to place caution indicators in first column

                fieldLayout.Fields.Remove(bkn);

                fieldLayout.Fields.Insert(0, field);

                fieldLayout.Fields.Insert(1, bkn);

            }

        }

This behavior only occurs if I am trying to insert at index 0, at which point it still visually appears to the right of the first column.  I attempted to “hack” it demonstrated on the else block above, but even removing and re-inserting the original first column despite re-inserting it at index 1 still kept the original column visually appearing first.  In short, I would like my newly inserted column to appear just before the column with the name “BKN”, even if BKN is originally the first column.
