Django Boolean Checkbox Input Field printing value='False' - django

Question

I have a number of Boolean Field checkbox inputs within a form and I have noticed the following Boolean Fields (avaialble, bfbw, asp and tours) are printing a default value of 'False' whilst the remainder of the Boolean Fields (para_athlete, working_with_children) do not.
When the value of False is there I cannot toggle the checkbox between on/off (True/False)
Is there something obvious that I am missing as I am struggling to see any difference between the fields?
Thanks in advance for any help I can get on this.
Below is the code.
Model
athlete_ref = models.CharField(max_length=10, default=1)
athlete_name = models.CharField(max_length=80)
email = models.EmailField()
phone_number = models.CharField(max_length=120)
home = models.CharField(max_length=120)
education = models.CharField(max_length=120)
sport = models.CharField(max_length=120, choices=sports, default='Shooting')
notes = models.TextField()
gender = models.CharField(max_length=120, choices=genders, default='Not Specified')
para_athlete = models.BooleanField(blank=True)
working_with_children = models.BooleanField(blank=True)
expiry_date = models.DateField(blank=True, null=True)
available = models.BooleanField(blank=True)
available_from = models.DateField(blank=True, null=True)
bfbw = models.BooleanField(blank=True)
latest_bfbw_session = models.DateField(blank=True, null=True)
number_bfbw_sessions = models.CharField(blank=True, null=True, max_length=10)
asp = models.BooleanField(blank=True)
latest_asp_session = models.DateField(blank=True, null=True)
number_asp_sessions = models.CharField(blank=True, null=True, max_length=10)
tours = models.BooleanField(blank=True)
latest_tours_session = models.DateField(blank=True, null=True)
number_tours_sessions = models.CharField(blank=True, null=True, max_length=10)
