Формсет сохраняет дубликаты записей

Моя система позволяет пользователю добавлять вопросы в форму при нажатии на кнопку Add More. Я использую набор форм для создания и добавления нового вопроса. Я пытаюсь сохранить набор форм в базе данных, однако при сохранении в базе данных я заметил, что есть дублирующиеся записи. Как предотвратить дублирование записей/ сохранить только новые записи из набора форм.
