No calculation of price component

Hi everyone,
Commerce Node Checkout module is exactly what I need for my site project, but the mechanism for calculating of the price components is not working properly.

I installed and configured the module as instructed. I've created several products of commerce_node_checkout type. For the selected content type I marked the "Applicable products" for Commerce Node Checkout settings. Then I added a rule for calculating the discount to the price of the product.

The created view with a list of products, display prices correctly. The product added directly to the cart, also displays the prices properly. Of course, node as a product should be added to cart through the creation of content, but now we know that the mechanism for price components calculating work properly.

Adding new content, choose a product from the list ( displayed price is wrong - without discount! ) and write a node. The product is added to the basket, but the price is calculated without components.
I checked only with a discount, but I do not know whether the taxes or VAT is calculated correctly?

Maybe I did something wrong?
Maybe I schould add special configured price calculating rules?
