I'm adding a new Field to a Form. It's a simple drop down with Yes or No, but by mistake I made the Field Required and then published it. I can't seem to find how to go back and edit this to make it unrequired. Any time I try to delete the Feild and start over, the system informs me (correctly) that the Field is required by the business. So, how do I either A) edit this field to no longer make it required or B) delete this field to start over and make a new field?
