Problem:
You have created an ACF select field and are trying to dynamically pass a list of posts filtered by language using a filter.
Solution:
We recommend creating a new variable to capture the current language using the WPML hook. You can find more information about this hook here: https://wpml.org/wpml-hook/wpml_current_language/
Example:

$current_language = apply_filters('wpml_current_language', NULL);

Then, use a conditional statement to filter the posts by the language code. Here are two examples of how you can implement this:

// Conditional switch statement based on the current language
switch ( $current_language ) {
    case 'fr':
        // your French post IDs        
        break;    
    default:
        // Default case for default language post IDs        
        break;
}

or

// Conditional logic based on the current language
if ( $current_language === 'fr' ) {
    // your French post IDs   
} else {
    // your English post IDs
}

If this solution does not resolve your issue or seems outdated, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. We highly recommend opening a new support ticket if needed.
