Django динамический набор форм сохраняет только последнюю запись

Я создал страницу, на которой пользователи могут вводить данные в формы, относящиеся к родительской модели (Patient) и двум дочерним моделям (CurrentMed и PastMed), связанным с этой родительской моделью.

В обеих дочерних формах используются динамические наборы форм, где пользователь может добавлять или удалять строки в форме. Моя проблема заключается в том, что только последняя строка наборов форм currentmed и pastmed сохраняется в моей базе данных, когда пользователь отправляет форму?

models.py

class Patient(TimeStampedModel):
    # get a unique id for each patient - could perhaps use this as slug if needed
    patient_id = models.UUIDField(primary_key=True, unique=True, default=uuid.uuid4, editable=False)
    
    name = models.CharField("Patient Name", max_length=255)

    creator = models.ForeignKey(
        settings.AUTH_USER_MODEL,
        null=True,
        on_delete=models.SET_NULL)


class Med(TimeStampedModel):


    med_name = models.CharField(“med name“, max_length=20)
    
    dose = models.IntegerField("Dose (mg)", default=0)

    timepoint = models.CharField(
        "timepoint", max_length=20,
        choices=[('current','current'), ('past', 'past')], default='unspecified')
    
    patient = models.ForeignKey(Patient, on_delete=models.CASCADE)

    class Meta:
        abstract = True


class CurrentMed(Med):
    timepoint = models.CharField(
        "", max_length=20,
        choices=[('current','current'), ('past', 'past')], default='current')
