You may want to clear out the values in your field list to either (1) reset the state of the document so it looks like a template, or (2) wipe the field values so you can enter new ones. To clear the values for all of your fields, follow these instructions:
Click the Clear all button and confirm that you'd like to clear all the values for your field.
Click the Populate button to set the fields in the document to bracketed text.
