"Add another" should not appear here:

I think this may actually be a js issue:
Loading failed for the <script> with source “http://localhost/static/admin/js/jquery.js”.
Loading failed for the <script> with source “https://perma-payments.com/static/admin/js/jquery.min.js”.

new theory max_num_forms should be 0, and is 1

<input name="subscription_request-0-subscription_request_response-MAX_NUM_FORMS" value="1" id="id_subscription_request-0-subscription_request_response-MAX_NUM_FORMS" autocomplete="off" type="hidden">
