{{user_cart}} Including Wrong Taxes

Hello, the email template I use {{user_cart}} to show the abandoned cart in the email. But for my emails, for some reason the guest emails that get sent include item prices and a total price that is 13% higher than the actual prices of the items in the cart.

I think this is because 13% tax is included in the price. But many of our customers have to pay taxes much lower than that, or none at all if they are from another country. So how do we make sure that {{user_cart}} only displays base prices? I don’t see the option anywhere, and the abandoned cart emails are useless to me if people think our prices are 13% higher than they really are.
