Mistake - Sum inkclude VAT in B2B primary group

[Meris]

Hi, I have a problem with Prestashop 8.2 and TAX. B2B group is enabled, a buyer is added and the default group B2B is selected. A tax rule TAX 0% has been created , assigned to which country to apply "no tax". Product category marked visible for B2B group. 
Result - B2B customer sees prices without TAX, adds to basket. Ajax has the correct amount in the basket without TAX. We click to go to the order and on the order basket page we see the same amount line already with TAX added. There must be an error somewhere. After all, the order in the pricing is marked group first, then country.... therefore the main B2B group should be calculated without TAX and the invoices generated without TAX.

This is not an error, this is the normal behavior of prestashop since the beginning, groups of customers without taxes see the prices without taxes but are billed with taxes. You must install this module (which also allows you to do your accounting) :  https://addons.prestashop.com/en/accounting-invoicing/27158-european-vat-number.html

However, this is either a mistake or deliberately done. If Ajax calculates correctly for the customer, why is there a 'fraud' in the TAX on the card? See the first photo.

Prestashop has been working like this since the beginning
