Как я могу решить эту проблему "нарушает ограничение not-null"?

Я всегда получаю эту ошибку, даже если ставлю значение по умолчанию для avg_winning_trade:

django.db.utils.IntegrityError: null value in column "avg_winning_trade" of relation "trading_summary" violates not-null constraint
DETAIL:  Failing row contains (43897354-d89b-4014-a607-a0e6ee423b52, 1, 2023-02-05 11:09:56.727199+00, null, 1, 19, 1, 0.00, null, -1.01, -1.01, 0, 0, 0.00, 0%, 0.00).

Второе нулевое значение - avg_winning_trade, которое вызывает ошибку здесь, я не знаю, почему оно здесь нулевое

это моя модель

class Summary(
  ActivatorModel,
  Model):

  user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, blank=True)
  starting_balance = models.DecimalField(default=0, max_digits=10, decimal_places=2)
  total_number_of_trades = models.PositiveIntegerField(default=0)
  total_number_of_winning_trades = models.PositiveIntegerField(default=0)
  total_number_of_losing_trades = models.PositiveIntegerField(default=0)
  total_number_of_be_trade = models.PositiveIntegerField(default=0)
  largest_winning_trade = models.DecimalField(default=0, max_digits=10, decimal_places=2)
  largest_losing_trade = models.DecimalField(default=0, max_digits=10, decimal_places=2)
  avg_winning_trade = models.DecimalField(default=0, max_digits=10, decimal_places=2)
  avg_losing_trade = models.DecimalField(default=0, max_digits=10, decimal_places=2)
  total_trade_costs = models.DecimalField(default=0, max_digits=10, decimal_places=2)
  trade_win_rate = models.CharField(max_length=10)

Это таблица
