Problems with price visualization in Cart

I set my E-commerce test site to show the Base Price only and it works fine in Categories/Product Detail pages.
In the cart I want to show the Base Price and the Tax amount but the cart does not show any kind of price.
I'm attaching you some screenshots of the configuration + Cart/Product page.
Please also note the Cart Module (left top side of the Product Detail screenshot) shows the Price + Tax amount.

Thanks in advance.

We don't have layout override for cart page, and we have it for product details page. What I'am saying is that your chart page is like in virtuemart by default. I think the problem is that simply you have to enable Final Sales Price because that is price shown in cart. Carts simply does not show Base Price because it calculates all taxes and discounts to show it there and you did not enable it's displaying so its empty.
