Thank you very much.
That so far seemed to do the trick.

Within admin, the order has both tax rates:
<<
Shipping: 5,75 €
MwSt.: 1,15 €
MwSt.: 3,10 €
Order Total:
37,00 €
Refunded: -0,00 €
>>
only it doesn’t display the value of the tax rates here (19% & 7%). In Woocommerce>Settings>Tax I have it set to Display Tax Totals> Itemized.

On the “Cart” Page – This is correct.
