ACF configuration

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is experiencing issues with ACF fields in a multilingual WooCommerce setup using WPML. Specifically, when updating a product in a secondary language, fields such as repeaters and relationship fields incorrectly inherit or duplicate content from the primary language product, despite being set to 'Copy once'.
Solution:
We recommend the following steps to address the issue:
1. Create a full backup of the site.
2. Navigate to

wp-content/plugins/sitepress-multilingual-cms/classes/custom-field-translation/class-wpml-copy-once-custom-field.php

and edit the

WPML_Copy_Once_Custom_Field::copy

method.
3. Replace the existing code with the following:

if ( ! get_post_meta( $post_id, 'copyoncedone' ) == 1 ) {<br />    add_post_meta($post_id, 'copyoncedone', 1 );<br />    foreach ( $custom_fields_to_copy as $meta_key ) {<br />        $values = isset( $custom_fields[ $meta_key ] ) ? $custom_fields[ $meta_key ] : [];<br />        if ( ! empty( $values ) ) {<br />            $values = array( $values );<br />        }<br />        $values = apply_filters(<br />            'wpml_custom_field_values',<br />            $values,<br />            [<br />                'post_id'                   => $post_id,<br />                'meta_key'                  => $meta_key,<br />                'custom_fields_translation' => WPML_COPY_ONCE_CUSTOM_FIELD,<br />            ]<br />        );<br /><br />        if ( empty ( $values ) && $source_element_id ) {<br />            $this->sitepress->sync_custom_field( $source_element_id, $post_id, $meta_key );<br />        }<br />    }<br />}

4. Save the changes and verify if the issue is resolved.

mortenS-12	I can still reproduce the error and we didn't edit anything. If you edit this new product i created: hidden link and change the product description (just add a word to it). You will see that the rows from the danish product in the "hvad" tab of the ACF fields, will be added (Now it won't have the content from the danish, but it will copy the rows). So the danish product has a row in these repeaters under the "Hvad" tab: "Hvad" - 1 row "Hvad second row" - 1 row "Hvad three columns" - 1 row The english version has no rows in any of them, if you update any part of the product it will add the rows in the repeaters. To recreate it after it happens, you can delete the rows on the english product. Update the product (everything is fine now) but when you again change any part of the product (like the product description) and update the product the second time, the removed rows will return. Note this is not only the "hvad" tab, it's also the other ACF fields on the products that does this. If the danish product has a row, but the english don't it will import the row to the english product after you change any part of the english product. Depending on the translation option(copy once, translate etc.), it will either import the row and the content or only the row.
