Multiple choice form field placeholder text

Hello, I am trying to make an additional form field with multiple-choice options on my demo request page. I added the button and all looks fine until you go to select an option and then the placeholder text/label appears as one of the options. There doesn’t appear to be any options with this particular type of button to remove it from those choice options…is there any workaround for this?
