Getting default option to show in combo box

I have a UMG script which generates a combo box list dynamically. It works for the most part. If you click on the little down arrow the options appear as expected. But I can’t seem to get the default option to show on the widget. It’s blank. Using ‘SetSelectedOption’ and ‘RefreshOptions’ didn’t do anything. Is this a bug?

Never mind. I found the problem. FYI: If you try to set the option text and it doesn’t exactly match one of the entries in the drop down list, it comes out blank.
