I solved my problem with the following function:

def __init__(self, *args, **kwargs):
    kwargs['csrf_enabled'] = False
    super(ProfileInfoForm, self).__init__(*args, **kwargs)

I added this function in ProfileInfoForm()

The issue was FormField includes csrf_token field as well as Actual form, i.e., RegistrationForm was also including csrf_token, so there were two csrf_token which were to be verified and only one was getting rendered actually in form. So, I disabled csrf_token in ProfileInfoForm so when FormField rendered it, it had csrf_token = False.

And RegistrationForm does have csrf_token enabled still now so the form is still safe.

My Guess is this does also required to be done in FormField as well.

FYI: This solution might be wrong due to my interpretation of the FormField code. SO please correct me if I am wrong in above solution.
