Набор форм Django действителен, но возвращает пустой список dict

Я пытаюсь создать форму, представляющую собой таблицу, в которой каждая строка содержит имя и флажок, позволяющий пользователю выбирать игроков для игры. Погуглив, я понял, что мне нужно сгенерировать набор форм, чтобы каждая строка в таблице была отдельной формой.

Наконец-то таблица отображается корректно и публикуется без ошибок, но я обнаружил, что, хотя набор форм действителен, очищенные данные содержат список пустых диктов. Я нашел несколько похожих постов на StackOverflow, в которых говорилось о создании собственного класса Formset и установке empty_permitted=True, но это не решило мою проблему.

Я не могу решить эту проблему, поэтому любая помощь будет оценена по достоинству.
