A django-phonenumber-field object is an instance of <class 'phonenumber_field.phonenumber.PhoneNumber'>, so you need to convert to a type string for django to present it.

There are several ways to do this, here is one of the ways.

Add the str method to your model:

def __str__(self):
    return f"{self.phone_number}"

From django-phonenumber-field it says:

The object returned is a PhoneNumber instance, not a string.

You should do something like:

def __str__(self):
    return str(self.phone_number)
