magento2 – Incorrect calculation of VAT on attributes

enter the description of the image hereHello, I hope you can help me.

I have a problem with the addition of a product price and a selected attribute (or more) price (s)

In this store I have entered the price / TAX settings: & # 39; VAT excluded & # 39 ;.

The product page is displayed correctly. However, once I select an option, the VAT attribute is added to the price of the product without including VAT.

This is not correct. See example The total sum should be 1185 euros.

See the following URL:
http://lectern.ae.mysleeve.hypernode.io/lectern-clear-and-frosted-berlioz

See code below; I think the calculation of the total price is wrong?
