hii the website may not be properly configured to handle different tax rates for each country. Ensure that each language is set to the correct country and tax rate in your site's settings. For example, Poland should use 23%, Hungary 27%, and Germany 19%. If it's still not working, you might need to check the tax calculation plugin or contact support for assistance.
