Background of the issue:
I am trying to update the product, clear the cache, change the template to the factory one, and disable plugins to resolve an issue with the currency converter. The issue can be seen on this page: hidden link.
Symptoms:
The currency converter does not convert currency for some products, just the symbol change
Thank you for your time. I'd appreciate it if you could confirm if the issue is happening on price range (variable) products only, or even the simple products with specific prices have the same issue.
If so, I'd appreciate it if you could provide login to staging version of the website (not live website) so we can do some investigative work there to identify the problem cause.
You can set the next reply a private to provide the info.
Also it will help if you can provide 2-3 more products that do not work for testing.
Thank you for the login info. I managed to login and checked the issue and there is a problem that you can test here:

If you go to the edit screen of the product and then click the Variations tab, and click on one of the variations you will see that the price item there is empty (check the screenshot)
That is like that for all other variation items.
So there is no price in Hungarian version in the first place for WPML to be able to do any sort of calculation for the converted currency.
Please test by adding prices for each variation in HUF and you save the product. Then make sure the translation is 100% complete for other languages and then the conversion should work.
