Hi,
In your products, you have a "tax category" setting in the "prices" area.
HikaShop will only take into account the tax rules for the tax category selected in the product.
I can see that you configured different tax categories for your tax rules.
Based on what you're saying, it seems that you selected "Default tax category" in the "tax category" setting of your products.
And thus, only the third tax rule, restricted to Poland, is taken into account.
You'll want to change the tax category for the other two tax rules to "Default tax category" so that they can be taken into account too.
