That is you should have this code in your functions.php finally:

// User role editor pro - Show all attachments for all roles
add_filter('ure_attachments_show_full_list', 'show_full_list_of_attachments', 10, 1);
function show_full_list_of_attachments($show_all) {
   //if (!current_user_can('hetbakenbeheren' or 'jaarboekje' or 'kerkdienstplanning')) {
    $current_user = wp_get_current_user();
    if (!in_array('hetbakenbeheren', $current_user->roles) && !in_array('jaarboekje', $current_user->roles) && 
        !in_array('kerkdienstplanning', $current_user->roles)) {
     return $show_all;
   }
 
   return true;
}

// ure_restrict_edit_post_type
add_filter('ure_restrict_edit_post_type', 'exclude_posts_from_edit_restrictions');

function exclude_posts_from_edit_restrictions($post_type) {
    $restrict_it = true;
    $current_user = wp_get_current_user();
    if (in_array($post_type, array('event', 'ctc_event'))) {
        if (in_array('hetbakenbeheren', $current_user->roles) && in_array('kerkdienstplanning', $current_user->roles)) {
            $restrict_it = false;
        }
    } elseif ($post_type=='ctc_sermon') {
        if (in_array('dominee', $current_user->roles)) {
            $restrict_it = false;
        }
    }
        
    return $restrict_it;
}
