Smart Coupons for WooCommerce

I have an Auto Generate New coupon code that is linked to a specific product. This Auto Generate coupon code is also set to Auto Apply and appear in the customer’s order in the cart when they are ready to use the coupon on next order. This auto apply is not working. I have to manually check auto apply in the coupon code that was generated after someone has ordered the specific product or the coupon code will not appear when the customer is ready to use the coupon code.

Please fix. It seems the auto apply on auto generated coupons does not work.
