Drupal commerce order total ignore changed unit price I have problem with commerce order total counting.

Every product has two prices (two fields). One price for everybody and second for exact role. I have rule which change prices if user with exact role is logged in. 

When i browse product with exact role all prices are ok. If i add some product to cart a go to my cart product prices and total price is still good. But when i go to checkout total price is set to 0.

In checkout are all products with good price but total price is 0.

Rule for changing price is simple:

event: calculate product price
condition: user role
action: set a data value (commerce-line-item:commerce-unit-price -&gt; second price field)


Do anybody know what could be wrong? Thanks for every advice.
Try to downgrade rules to v 2.7. For more details look at https://www.drupal.org/node/2408705


  Important: Rules 2.8 has a critical regression that causes checkout
  rules to not work. Follow #2403851: Commerce pricing rule not working
  for more details, and downgrade to 2.7 for now.
