Get Wordpress/ACF options on child pages

I use Wordpress with Timber (as template renderer), and Advanced Custom Fields. I'm struggling with some sub page options.

My problem is that I can't get the options on the right posts (my jobs) – it's only available on the job overview page.

I've created an options sub page to my custom post_type "job", like so:

if (function_exists("acf_add_options_page")) {
    acf_add_options_sub_page(array(
        "page_title" => "Job options",
        "menu_title" => "Job options",
        "menu_slug" => "job_options",
        "capability" => "edit_posts",
        "parent_slug" => "edit.php?post_type=job"
    ));
}

And I'm able to get that options on the job-overview page, like so:

$context["options"] = get_fields("options");

But when I run that same command on the posts with post_type "job", then it returns null.

How can I get that options to affect the posts with post_type "job" and not the overview?
