ValueError: Cannot query "": Must be "Group" instance. Django

Добавил пользователя в django с правами на просмотр групп и шкафчиков. После этого вышел с админки и решил зайти под этим пользователем, дабы посмотреть, как будет выглядеть. Сразу же, после авторизации вылетела такая ошибка:

Скорее всего это связано с тем, что я дополнял группы доп. полями. Мой admin.py:
