Translated string is not translated on Woocommerce checkout page

Hi,

I inserted the function pll_register_string into the functions.php file of the plugin Theme Customisations to register a string. I use the plugin Theme Customisations because I use the Boutique child theme for Woocommerce and I don’t want my changes be overwritten with the next update of the theme.

The string appears in the Polylang translated strings table and I translated it from German to English. But the string does NOT appear as English string on the Woocommerce checkout page. Only the German version appears.

It would be nice if someone could help me.

Thanks a lot in advance.

Best regards

Albert
