só aparece o custo do frete quando temos apenas um produto no carrinho

Hello

We’re trying to use your plugin, which shows the freight cost separated by class.

We realize that you do not charge for it, but we are willing to pay to be able to use it in the right way if possible.

At the moment only appears the cost of freight when we only have one product in the cart, when we put two products being one of different classes ai does not show anything. It should show the cost of freight of each class, as seems to me to be the purpose of the plugin.

Follow the screens the way we set up, to see if they are correct.

Overcoming this step, then we will move on to the next which is to show the freight by product, we will also need more complex calculations.

Thank you very much, I count on your help!!!
