Cart Price displaying WRONG!

I am using Woocommerce Blocks to improve the cart page. The thing is everything works great, except when we enter a discount code.

When we introduce a discount coupon, in addition to subtracting the total amount of the cart, the proportional part of the price of each product is discounted.

For example:

If we have a product that is 5.95e, the total of the cart is 5.95e. If we enter a code of 5e, the total of the cart and the total of the product will go to 0.95.

If we have 5 products of 5e, the cart total is 25e. If we apply a code of 5e, the total will go to 20e but also, each product will discount 1e.

With the woocommerce shortcode this does not happen, so I deduce that it is a plugin problem.

Any idea on how to solve taht?

You can use 123456 as coupon code to test
