WPCS shortcode doesn’t work on translated pages using WPML

Hi.
I started using WPML to translate my sites and I noticed that translated pages using the WPCS shortode (for example: [wpcs_price value=4]) aren′t showing the price, and only the shortcode is visible (https://snipboard.io/7LxCze.jpg). Original pages show the price correctl (https://snipboard.io/2tUGCV.jpg).
I found this page on your site: Switch currency with language change (https://wp-currency.com/switch-currency-with-language-change/), tried to add the code in functions.php, but my site broke and threw a fatal error message.

Can you please help?
Thanks
