My webform is generating radio buttons instead of select fields. Does anyone have any idea what might be causing this?
When you are editing that field, look down at the very bottom under display and make sure "Listbox" is checked. It is the one that says:
Check this option if you want the select component to be of listbox type instead of radio buttons or checkboxes.
You didn't say what version of the module you are using, but this should be accurate for all current versions. In the future it would be a good idea to include what version you are having the issue with when asking for help.
