[Resolved] Finding intermediary post custom fields

I'm trying to display the titles of custom post types that are linked to an intermediay post via an intermediary post custom field.

Custom Post Types are:
Leerling (student)
Locatie (location)
Workshop

Intermediary Post Type
Leerling (parent) - Locatie (child)

Custom field
workshop-leerling-locatie (single line)

Students choose per Location which Workshop they wanna attend, which is stored in the Intermediary Post Custom Field as the Workshop post ID. I would like to show on my page (it will become a csv file eventually) all the choices any student made for each of the Locations.

Ideally I would have used a view, but as nested shortcodes apparently don't work (i.e. [wpv-view name="test" wpvrelatedto="[wpv-post-id]"]), I had to resort to a custom shortcode. Here is that code:

add_shortcode('get_student_choices', 'func_get_student_choices');
function func_get_student_choices($atts) {	 
  $result = "";
  
  $leerling_id = do_shortcode("[wpv-post-id]");
  $dagschema_id = do_shortcode("[wpv-post-id item='@dagschema-leerling.parent']");
  
  $cur_students_locs = toolset_get_related_posts(
                       $leerling_id,
                       'leerling-lokatie',
      [ 'return' => 'post_object',
        'query_by_role' => 'parent',
        'role_to_return' => 'intermediary',
      ] );
  
  $results = count($cur_students_locs);

  foreach ($cur_students_locs as $studentlocation) {
    
    print_r($studentlocation);
    $results = $studentlocation["ID"];
  }
  
  return "<td>" . $results . "</td>";
}

But whatever I do, I don't seem to get results from the $studentlocation inside the foreach.

What am I doing wrong? Hope you can help!
