SfMultiColumnDropDownControl Grouping Selection Exception

If you programmatically set the GroupColumnDescriptions for the grid in the drop down like this:

sfddControl.GetDropDownGrid().GroupColumnDescriptions.Add(new GroupColumnDescription { ColumnName="Column1Text" });

When you click an item inside of a group it will throw this exception:

"System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index\r\n   at System.ThrowHelper.ThrowArgumentOutOfRangeException()\r\n   at System.Collections.Generic.List`1.get_Item(Int32 index)\r\n   at System.Collections.ObjectModel.Collection`1.get_Item(Int32 index)\r\n   at Syncfusion.Data.RecordsEntryList.get_Item(Int32 index)\r\n   at Syncfusion.Data.TraversalHelper.GetPrevious(NodeEntry entry)\r\n   at Syncfusion.Data.GroupDisplayElem" string

but if you set the style and add in the GroupColumnDescriptions using XAML it works fine.
