Product tax calculation not working properly

[TR mediendesign]

Hello,

I got a quite simple product setup but the tax calculation is not working as expected. In the shop there are two products:

1) Regular Ticket, 25 € incl. 7% VatTax
2) VIP Ticket, 55 € incl. 19% VatTax

The VIP Ticket needs to be sold in addition to the Regular Ticket, so I tried to create a product bundle. When opening the Regular Ticket, the product bundle is shown but the additional price is not calculated as it should be.
The base price of the VIP ticket is 46.218487 € and the additonal cost should be 55,00 €. Instead it shows + 49,45€ so it uses the 7% VatTax instead of the 19% VatTax. It doesn't matter whether the VIP Ticket is a child product of the Regular Product or not. The cart also shows both tax rates, which is good, but the shown values are incorrect as well.

Important: I cannot create a product for the total price of 80 € incl. 19% VatTax because this is not correct in Germany. It has to be calculated partially using the proper tax rates.

Current Virtuemart version: VirtueMart 4.2.18 11050

Kind regards,
Tobias

How do you create your bundle?
