Custom Button Issue

Hello,

I seem to be having some issues with using an image as a custom button with this Stripe plugin.

Here are the issues:
1) It’s reading the default CSS styling, even though the button has it’s own css class, “cta50”

2) It is still displaying “Buy Now”, even though I deleted the button_text=”Buy Now” in the short code.

This is the short code:
[accept_stripe_payment name=”Elite Membership Level” price=”50.00″ class=”cta50″ description=”Elite Level Package $50 USD” item_logo=”http://unlimitedincomeforyou.com/wp-content/uploads/2017/09/elite-level-package.jpg” url=”http://unlimitedincomeforyou.com/index.php?/register/YZdv72″%5D

Any thoughts would be appreciated! Thank you.
