[Resolved] Repeaters & Flexible content generated with acf_add_local_field() and WPML

Hello,

I want to report a bug regarding ACF. It implies that the repeaters and flexible content fields do not display in sites powered with WPML when visiting a translated page in any secondary language. Here are the steps to reproduce it :

1) Create a simple repeater field in functions.php or other using acf_add_local_field_group().

<?php
add_action( 'acf/include_fields', function() {
if ( ! function_exists( 'acf_add_local_field_group' ) ) {
return;
}

acf_add_local_field_group( array(
'key' => 'group_65df8b71d1c1a',
'title' => 'Test Repeater Group',
'fields' => array(
array(
'key' => 'field_65df8b716e6aa',
'label' => 'Test Repeater',
'name' => 'test_repeater',
'aria-label' => '',
'type' => 'repeater',
'instructions' => '',
'required' => 0,
'conditional_logic' => 0,
'wrapper' => array(
'width' => '',
'class' => '',
'id' => '',
),
'wpml_cf_preferences' => 1,
'layout' => 'table',
'pagination' => 0,
'min' => 0,
'max' => 0,
'collapsed' => '',
'button_label' => 'Add',
'rows_per_page' => 20,
'sub_fields' => array(
array(
'key' => 'field_65df8b916e6ab',
'label' => 'Element',
'name' => 'element',
'aria-label' => '',
'type' => 'text',
'instructions' => '',
'required' => 0,
'conditional_logic' => 0,
'wrapper' => array(
'width' => '',
'class' => '',
'id' => '',
),
'wpml_cf_preferences' => 2,
'default_value' => '',
'maxlength' => '',
'placeholder' => '',
'prepend' => '',
'append' => '',
'parent_repeater' => 'field_65df8b716e6aa',
),
),
),
),
'location' => array(
array(
array(
'param' => 'post_type',
'operator' => '==',
'value' => 'page',
),
),
),
'menu_order' => 0,
'position' => 'normal',
'style' => 'default',
'label_placement' => 'top',
'instruction_placement' => 'label',
'hide_on_screen' => '',
'active' => true,
'description' => '',
'show_in_rest' => 0,
'acfml_field_group_mode' => 'advanced',
) );
} );
?>

2) Create a page and fill in the repeater with content. Publish and translate the page in a secondary language with WPML.

3) On the page, var_dump() the fields with get_field(). You can try using the field name and then the field key.

You will notice that the fields are returned correctly in the primary language, but not in the secondary language. From my testing, the issue also extends to Flexible Content.

I noticed that, in the wp_postmeta table, there are missing entries for the post in the secondary language. Namely, all the entries that start with a underscore "_" followed by the field name that are involved in the repeater/flexible content created earlier are missing.

As WPML is advertised as fully compatible with ACF, I would hope that you could look into this issue. I hope this provides enough insight regarding the issue. If you need any more details, please let me know and I will provide any additional detail required.

Thank you very much for your time and consideration.
