Price are displayed out of tax on for variable products on quickshop

Hi, as you can see following this link, I have some troubles with price configuration : https://ifri.bily.fr/categorie-produit/gazouz/

As you can see on the 2nd product ‘Gazouz Orange’, the pice is beetween 8,44€ and 12,66€ which is the including tax price and which is the price I want to display. But when I click on ‘select option’ to add product to cart from this page, when I select a variation the little price is displayed out of tax. For instance for ‘6×1,25L’ variation the displayed price is 12€ which is the out of tax price instead of 12,66€ which is the including tax price. I would like this price to be displayed including tax.
