Payment button not shown

I am testing out the Pie Register.

I have set up the payment gateway.

In the manage forms section, I see both the Submit and Paypal button. I don’t seem to be able to delete the Submit button.

On the live site, I can only see the Submit button.

When I fill in the form and Submit, I get the error – “Please select any payment method”.

What am I missing ?
