Hello David,
Thank you for writing.
What I meant in my previous reply is that it is normal to see the "Telerik.WinControls...." text when the
RadMultiColumnComboBox control is bound (to a
DataTable for example) and its
DisplayMember is not set accordingly. In this case, instead of the row values, you will see this text.
However, it seems that there is an issue, when the selected item is null. I am logging it in PITS and we will address it in a future release. Here is a link to the item, where you can vote for it and also subscribe for its status updates:

Indeed, you are correct that Bang probably has the same issue.
Meanwhile, what you can do to work around this issue is to remove the text manually when such case appear:
I have updated your Telerik points for this report.
Should you have any other questions or suggestions, do not hesitate to contact us.

Stefan
