TAX would not be shown at products

-- HikaShop version -- : Business 2.4.0
-- Joomla version -- : 3.4.1

Hi,
our shop was only for german customers. I added austria as second country, but then, there was no tax shown at the products. I'd deactivated austria, but the tax still not be shown at the products. All settings are right, the main country is germany, the vat category is setting right, the tax is german, the shipping module is german.
Can you help me please?
Best regards
Ollie

ok, I'd found the solution in an other thread. I reinstalled the version 2.4.0 with a new downloaded version.
I deleted the "customer type" selection of your tax rule. After this it works.
But this is not a great bug ...
Best regards
