To remove a Woodpecker field from your document, just delete the text that Woodpecker inserted within the document.
The text that Woodpecker inserts into your document when a field is inserted can be selected with your mouse cursor. Once you select it, just press the "delete" key on your keyboard.
The next time you click "Populate", Woodpecker will check to see if the field still exists. If not, Woodpecker will update the counter for the field (the little number next to the field name).
