Django dynamic forms validation - django

Question

So I am new to Django and I have created a View which uses a total of 8 forms dynamically. There is one base form which is always displayed and then there are 7 more forms that are displayed only if user selects that option from a drop down (drop down is in the HTML template).
I am now trying to validate the form fields and when I display all 8 forms statically, the validation (clean methods) for each of the forms work perfectly! However when I change that to dynamically display the forms based on user selection, the validation for the base form fails every time.
Any idea why that could be happening? I could provide instances of the forms/view if that would help!
Template:
<form0 id="BaseForm" action="/test_created/" method="post">
{% csrf_token %}
{{create_test_form.as_ul}} <br><br>
</form0>
<form1 id="vc1Form" action="" method="post" style="display:none">
{% csrf_token %}
{{vc1_form.as_ul}} <br><br>
</form1>
<form2 id="vc2Form" action="" method="post" style="display:none">
{% csrf_token %}
{{vc2_form.as_ul}} <br><br>
</form2>
<form3 id="vc3Form" action="" method="post" style="display:none">
{% csrf_token %}
{{vc3_form.as_ul}} <br><br>
</form3>
<form4 id="vc4Form" action="" method="post" style="display:none">
{% csrf_token %}
{{vc4_form.as_ul}} <br><br>
</form4>
<form5 id="vc5Form" action="" method="post" style="display:none">
{% csrf_token %}
{{vc5_form.as_ul}} <br><br>
</form5>
<form6 id="vc6Form" action="" method="post" style="display:none">

</form7>
<div>
<select id="validation_classes_id" name="all_validation_classes" onchange="showForm()">
