Django distinct query все еще возвращает дубликаты

У меня есть список покупок, который я могу заполнить, добавив все ингредиенты из рецепта. Я хочу запросить Shopping, чтобы получить все уникальные рецепты, присутствующие в списке покупок, однако мой отчетливый запрос возвращает дубликаты

#query
ShoppingItems.objects.filter(user=account, shoppingList=shoppingList, recipe__isnull=False).values('recipe').distinct()
#returns > <ShoppingItemsQuerySet [{'recipe': 47}, {'recipe': 47}, {'recipe': 47}, {'recipe': 47}, {'recipe': 47}, {'recipe': 47}, {'recipe': 47}, {'recipe': 47}, {'recipe': 47}, {'recipe': 47}]>
