Django extract field form html - django

Question

I have a html page that returns data in a form. The forms is a multiple choice checkbox field with "name=states1". When I run print(vars(self)) in my forms.py I see that the data is there ['MD', 'WV', 'WY'] (see below) however, when I try to extract it with print(self.data['states1']) I just get 'WY' and print(len(self.data['states1'])) returns 2.
{'instance': <AA: AAobject>, '_validate_unique': False, 'is_bound': True, 'data': <QueryDict: {'csrfmiddlewaretoken': ['AAAAA']: ['1'], 'states1': ['MD', 'WV', 'WY'], 'states': [''], 'price': ['2.00'], 'user': ['1', '1']}>, ...
However, when I run
import json
print(json.dumps(self.data, indent=2))
I get the following output
{
"csrfmiddlewaretoken": "AAAAA",
"roles": "1",
"states1": "WY",
"states": "",
"price": "2.00",
"user": "1"
}
The data is just gone. Why is my data being restricted to the last field, when I can clearly see it when looking at vars?
forms.py
class UserProfileChangeForm(forms.ModelForm):
states = forms.CharField(widget=USStateSelect(), initial='TX', required=False)
class Meta:
model = SkilledLaborer
fields = ['user','roles','travel_flag','price','states']
def clean_states(self):
print('states')
states = self.cleaned_data['states']
print(type(vars(self)))
print(vars(self).keys())
print(vars(self))
print(self.data.keys())
print(self.data['states1'])
print(len(self.data['states1']))
import json
print(json.dumps(self.data, indent=2))
try:
self.data['states1']
except:
pass
return states
