Tax fee not being calculated in product page

Dear devs,
I tried your plugin with checkboxes, radios, etc. and if I select “Fixed Fee Taxable?” it does not tax it, at all. I would like to see in the product page the added options and the tax calculated shown separately, to make a unique total taxed price at the bottom when a user add the product to cart.

EDIT: I tried selecting both “Fixed Fee” and “Fixed Fee Taxable”, to select just one of them respectively, to uncheck both and nothing. The prices are not shown taxed.
In my WooCommerce settings, I input a taxed price and WooCommerce show me the taxed and untaxed automatically. Is it possible to do the same here? I put a taxed price and the software shows how much tax has been applied in the summary overview at the bottom of the product page, eventually showing the total taxed.
