Old_field = model_state.fields.pop(self.name) KeyError: when migrations

Я получил эту ошибку

$python manage.py makemigrations

KeyError: 'is_year_set'

даже

$python manage.py migrate shows the same error.

Проведенные мной проверки.

$python manage.py showmigrations

Все миграции применяются, но я сделал python manage.py migrate --fake до того, как произошла ошибка.

в models.py

is_year_set - комментарий удален.

is_type_set = m.BooleanField(choices=TYPE_SET_CHOICES,default=False)
#is_year_set = m.BooleanField(choices=YEAR_SET_CHOICES,default=False)

Почему makemigrations commanad все еще требует is_type_set? и как я могу решить эту проблему?
