Not showing discounted price correctly on category

Hi

I created a discount.
I want it to show in both with old and new price in :category and product view
In Display > Default parameters for Product > Show discounted price: Display the price before the discount is applied
On the product page it shows correctly with the old and new price: Check it here
Now to the problem:
On the category page it does not show correctly - it shows the amount of the discount and says: -20€ but I want it to show the old and new price too... how do I achieve that as I can not find this same setting in the Default parameters for categories. Please check it here

Hi,

Edit your menu item via the Joomla menu manager and look at the "product options" tab. There, you'll have the "discount" setting that you can configure for the listing of products.
