This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is experiencing issues with tax calculations and currency conversions in their multilingual and multicurrency setup using WPML. The problems are specifically occurring with Google feeds and in the accounting system where taxes and currency values are incorrect for orders in languages other than the main one.
Solution:
We recommended the client to install a specific plugin on a test site to help diagnose the issue. We provided a link to the test site and asked the client to notify us once the plugin installation is complete. This step is crucial to replicate and understand the problem better.

If this solution does not resolve the issue or seems irrelevant due to updates or different circumstances, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If problems persist, please open a new support ticket at WPML support forum for further assistance.

The listed site above doesnt work correctly with the taxes, we use the Multilingual and multicurrency plugin from WPML, but for the past 2 weeks we've been having difficulties with price convertions in Google feeds and taxes, the front of the site and prices look good.

All the orders beside the main language are bad, CZ/HU/RO/PL etc... You can see in the screenshot above that the taxes in our accounting system show different tax prices for other parts of orders or COD payment..

Another issue beside taxes is the currency, it sometimes calculates whent he payment isnt cod, the TAXes correctly, but the currency is completely changed, see our Accounting system screenshot again with the 2 products in the order
