Since we’re having the same issue, I’ll post an example of PHP-registered ACF fields that are not indexed.

Of course is this an example. Other field types should be also indexed (textarea, wysiwyg, etc).

Following PHP code is placed in a file and that file is included by functions.php.

<?php

acf_add_local_field_group([
    'key' => 'group_page_settings',
    'title' => 'Pagina instellingen',
    'fields' => [
        [
            'key' => 'field_custom_title',
            'label' => 'Aangepaste titel',
            'instructions' => 'Gebruik <strong><em>...</em></strong> voor ge&auml;ccentueerde tekst.',
            'name' => 'custom_title',
            'type' => 'text',
        ],[
            'key' => 'field_custom_subtitle',
            'label' => 'Subtitel',
            'name' => 'subtitle',
            'type' => 'text',
        ],
    ],
    'location' => [
        [[
            'param' => 'post_type',
            'operator' => '==',
            'value' => 'page',
        ]],[[
            'param' => 'post_type',
            'operator' => '==',
            'value' => 'post',
        ]],
    ],
    'menu_order' => 10,
    'position' => 'acf_after_title',
    'style' => 'default',
    'label_placement' => 'top',
    'instruction_placement' => 'label',
    'hide_on_screen' => '',
    'active' => 1,
    'description' => '',
]);
