NSMatrix has too many buttons?

I'm trying to make a radio button set with two options, "Single" and "Sweep". I dragged a radio button into my storyboard and then added it to a matrix using Editor->Embed in. I then changed the number of rows to two.

I see two radio buttons in the IB display, the Inspector says there's two rows, and when I run it I only see two buttons. However, there are three buttons in the hierarchy display:

enter image description here

It seems the second one named "Single" is real, when you click on the lines in the left pane you can see a shadowed selection appear in the same place as the first button. I tried everything I could to delete that entry, but nothing seems to work.

This may simply be a IB bug that I should report, but I'm not sure I simply didn't do something wrong in setting this up. Anyone else seen anything like this?

The first cell under the matrix in the document outline is the prototype cell. From the NSMatrix Class Reference:

The prototype cell that’s copied whenever the matrix creates a new cell.

NSMatrix has a bunch of methods like addRow and insertColumn: that make copies of the prototype.
