Problem with the product list display when i change the price field settings

In a fresh install when i go to 'admin/commerce/config/product-variation-types/bags-cases/display/node_product_list' and uncheck the 'Show calculated price' of the price field, the price of 'Drupal Commerce iPhone Case' at 'collection/geek-out' page is changed to the based one (22,00). The problem is that when i change back the above option (check the 'Show calculated price' again as was at the first place) the price of 'Drupal Commerce iPhone Case' at 'collection/geek-out' page isn't changed back respectively (to 26,40).

The only way i found to show the right price is to change the format of the price field to 'Formatted ammount' and check the setting 'Display the calculated sell price for the current user.'. Only then the price changes back to 26,40 at 'collection/geek-out'.

This is the first time i use the Commerce Kickstart module so maybe i am doing something wrong..
