Can't assign different prices to the product's Tax included and Tax excluded fields

[vascomarques6]

Hello there,

I'm trying to integrate products on my PrestaShop via API. When it comes to pricing, there is only one field, called price, to be assigned. When I assign a value to this field, on the backoffice, it shows two different text boxes, one called Tax Included, and another one called Tax Excluded. Whatever value I assign to 'price', both Tax Included and Tax Excluded are assigned the same value. Also, this value is not affected at all by which tax rule is applied to it. To add to it, whenever I try to manually change either Tax Included or Tax Excluded directly on the backoffice, it automatically changes the other one. I am wondering if there is no way of distinguishing both of these fields, as it makes a big mess when it comes to taxation.

 

Thank you for your time.
