Custom String Translation

I am using the Inspiro (child) theme and am trying to translate the hero_title and hero_description.

After adding the below php, only 1 string showed up under “Translate Strings”, hero_description, but entering the translated text here does not display it on the actual page.

Am I doing something wrong?

add_action(‘init’, function() {
if(function_exists(‘falang_register_string’)) {
// Hero section strings
falang_register_string(‘inspiro_child_theme’, ‘hero_title’, get_theme_mod(‘hero_title’));
falang_register_string(‘inspiro_child_theme’, ‘hero_description’, get_theme_mod(‘hero_description’));
}
});

The page I need help with: [log in to see the link]
