When I uncheck Final Price, then no Totals are displayed on checkout cart

[designerPT]

I have a Group of registered clients that i want to show only the Prices without Tax.
So i disabled the Final Price checkbox and enable Price Without Tax.
When i disabled the Final Price, no totals are displayed on checkout cart.
How can fix it?

In an older version it works fine.

That is because total is final price. You can exclude a specific from tax so price without tax and sales price is the same.
