[Решено] It does not display the correct currency in Google search.

Background of the issue:
I am trying to display the correct currency for products on my website, which is translated with WPML into several languages. The primary language is English with Euro as the currency, and the site is also translated into Bulgarian with BGN (Bulgarian Lev) as the currency. I expect the product prices to display in Euro for English searches and in BGN for Bulgarian searches.

Symptoms:
When I search for a product in Google in Bulgarian, the price is calculated correctly based on the exchange rate but is displayed in Euro instead of BGN.

Questions:
Could you please let me know where this issue comes from?
How can I fix the currency display issue for Bulgarian searches?
