[QUESTION] backward relation duplicates ?

I have the following models:

`

class PerfilDoctor(models.Model):

     id = fields.UUIDField(pk=True)
     usuario = fields.OneToOneField('models.UserModel', related_name="user_profile", on_delete=fields.CASCADE)
     descripcion = fields.CharField(max_length=500)

class Clinica(models.Model):

    id = fields.UUIDField(pk=True)
    cliente = fields.ForeignKeyField('models.UserModel', related_name="cliente_clinica", on_delete=fields.CASCADE)
    nombre = fields.CharField(max_length=50)


class Puntuacion(models.Model):

     id = fields.UUIDField(pk=True)
     doctor = fields.OneToOneField('models.PerfilDoctor', related_name="doctor_puntuacion", on_delete=fields.CASCADE, null=True)
    clinica = fields.OneToOneField('models.Clinica', related_name="clinica_puntuacion", on_delete=fields.CASCADE, null=True)

And when I run the code gives me this error:

tortoise.exceptions.ConfigurationError: backward relation "doctor_puntuacion" duplicates in model PerfilDoctor

Any idea why it's happening ? thank for your help!

Start with the PerfilDoctor, Clinica, and Puntuacion model definitions shown in the issue and trace how their related_name values are registered. Reproduce the ConfigurationError using this model setup; done should be a clear explanation of why doctor_puntuacion is duplicated and whether the behavior requires a project change.
