Alipay problem

Hi

I install the plugin and use Test API test my site with stripe and Alipay option. After I enabled alipay. Go to checkout page and click “Pay via Alipay”. And then redirect to stripe.com and I clicked “Authorize Test Payment”. Then redirect to my site and I clicked “Place Order”. The stripe form only some field to insert my card number, MM/YY and CVC. No any options to choose Alipay!! with no any price in the form. Also many messages in console such as:

“StripeCheckout.open: Type mismatch for option ‘billingAddress’:
Looking for type ‘boolean’, but instead we found ‘undefined’.
You can learn about the available configuration options in the Checkout docs:
https://stripe.com/docs/checkout”

Wordpress: 4.8.3
Woocommerce: 3.1.2
Stripe Payment Gateway for WooCommerce ( Basic ): 3.0.4
