Мой код Kivy не обнаруживает установку флажка ⇐ Python

[Anonymous]

Недавно я попробовал Kivy для личного проекта, который хотел реализовать: приложения, позволяющего создать персонажа DnD с некоторыми деталями. Этот персонаж будет храниться в файле JSON и загружаться на главном экране. Проблема в том, что при использовании флажков для выбора пола это вообще не работает, и я не могу найти проблему.
Вот файл main.py:

Мне бы хотелось, чтобы приложение позволяло вам устанавливать и снимать флажки, но ограничивало выбор только одним полем (только один пол).
Сам код тоже может быть очень запутанным, но на данный момент он работает нормально XD
