I want to pull the fields of the option pages based on the language, but I get the default language back every time.

This is how I register an options page:

acf_add_options_page([
    'page_title' => __('Allgemein', 'theme'),
    'menu_title' => __('Allgemein', 'theme'),
    'menu_slug' => 'site-settings',
    'redirect' => false,
    'show_in_graphql' => true,
    'graphql_field_name' => 'siteSettings',
    "position" => 2,
]);

I used ACF to create the fields for the options pages.

I have entered different content for each language.

DE

Default:

EN:

Nevertheless, I always get the following back:

EN | DE | Default:

Am I doing something wrong?
