Hello,
It looks like the HikaShop bundle system do not process the taxes.
If you take a look in your database, for the table "order_products", you'll see the entries for the "order_id" of your test order.
Some products have a "order_product_quantity" set to 0 ; these are the products of the bundle (they also contains some content in the column "order_product_options").
HikaSerial list all the products of the order which allow the plugin to get the product content.
The price (inc vat) is the order_product_price plus order_product_tax.
If the order_product_tax stays 0, the plugin think it gives you the correct price with the tax, since it's performing the addition.
Best would be to open a new thread in the HikaShop section of the forum so the HikaShop support team will be able to take a look at it.
