Error with Advanced Dynamic Pricing for Woocommerce

Hello,
I’m working with the Multi Currency Plugin and it works fine by its own, but I need a dynamic pricing plugin, so I installed the one mentioned above.
I added the rules for that plugin (img02). the first line is just so the rule just applies to certain users [that was just a test(img03)] and the second rule is for it to be applied when the costumer buys a dozen up to 20 pieces of a product, they should get a 10% p.e. (img04).
It does work but then on the cart, I see the rules apply for that product, but if I have another product it changes its price, but just on the description, because the total is correct (img05).
