VirtueMart 3.4.2 - Joomla! 3.9.8 - php 7.2.10
I've a "+60€ tax" in an event category : if i buy one or more product of this category, a DBTaxBill is created with +60€ in my cart. It works fine.
But if I add another product to my cart, like a book, the tax is overwriten and no tax appears.
I tried by creating a "0 € tax" for books, but this "0 € tax" stays as the last tax, when a book is the latest added product of the cart.
If i had another product of my event as a "last cart product", the "+60€ tax" appears.
Thanks
