Problem with pricing rules

Hi Guys. I have a problem with product prices when the product has discount price.
If I set up pricing rules for fields then regular price become the same as discounted price. For example my product costs normaly 100$ and is discounted to 60$. Normally it shows this way: “100$ 60$”. But if any pricing rule is active it shows up like this: “60$ 60$” . Then when I check checkbox for example adding extra 10$ for extra something then price shows up this way: “70$ 70$”. Is it possible to fix it to looks like it should be so: “110$ 70$” ??? I tried with simple and variable products. The same happend. When pricing rules are not set everything is fine but if set, strikethrough regular price show the same price as discounted price…
