Choice contol having first option selected

Was this form generated via K2 Application or custom build?

Is the Default value empty in SharePoint?
 

If the form was generated and you made a change to the column setting, does it give you the option to regenerate?
 

What is the data source for the control?  Is it the GetFieldMetaData method?
 

The form was a custom build.
From the beginning the standard choice was None.
See attachments.
 

I just fixed it.It turns out that the regenerated settings aren't pushed to a custom SmartForm by default.I deleted the old control and dragged it anew onto the SmartForm.That solved it. :)
