Translation of Clone field

Hello,

I’m trying to translate a page with a cloned field but i have a bug.

I installed a fresh wordpress to try, with these plugins only :

– Advanced Custom Fields Multilingual
– Advanced Custom Fields PRO
– WPML Multilingual CMS
– WPML String Translation
– WPML Translation Management

I am following the instructions here :

https://wpml.org/documentation/theme-compatibility/setting-wpml-advanced-custom-fields/

But when i try to save my duplicated page, i get an error :

Warning: array_merge(): Argument #2 is not an array in MYWEBSITE/wp-content/plugins/advanced-custom-fields-pro/pro/fields/clone.php on line 230

Fatal error: Uncaught TypeError: Argument 1 passed to WPML_TM_ACF::build_fields_names() must be of the type array, null given, called in MYWEBSITE/wp-content/plugins/wpml-translation-management/classes/compatibility/acf/class-wpml-tm-acf.php on line 116 and defined in MYWEBSITE/wp-content/plugins/wpml-translation-management/classes/compatibility/acf/class-wpml-tm-acf.php:110 Stack trace: #0 MYWEBSITE/wp-content/plugins/wpml-translation-management/classes/compatibility/acf/class-wpml-tm-acf.php(116): WPML_TM_ACF->build_fields_names(NULL, Array) #1 MYWEBSITE/wp-content/plugins/wpml-translation-management/classes/compatibility/acf/class-wpml-tm-acf.php(57): WPML_TM_ACF->build_fields_names(Array) #2 MYWEBSITE/wp-content/plugins/wpml-translation-management/classes/compatibility/acf/class-wpml-tm-acf.php(33): WPML_TM_ACF->update_custom_fields_settings(Array) #3 MYWEBSITE/wp-includes/plu in MYWEBSITE/wp-content/plugins/wpml-translation-management/classes/compatibility/acf/class-wpml-tm-acf.php on line 110

When i try to debug the clone.php file, i made a var_dump of $field_group_fields (l227), which is null, because the acf_get_field_group($selector) (l222) fails.
The $selector value is equals (in my case) at group_57fe54dc67b52, which is my French (first language) clone group, and not the translated one !

My 2 ACF export files (French and English) :

French (original) :

SO, it seems that even if the fields are correctly configurated, ACF tries to get the french clone when i save the english (duplicated) page.

I made a video showing the bug : http://helloddk.com/acf-wpml.html (or direct link : http://helloddk.com/acf-wpml-bug.mp4)

I found this ticket on the WPML forum which seems related : https://wpml.org/fr/forums/topic/les-champs-acf-de-type-clone-apparaissent-vide-sur-le-front/

Can anyone help me ?

Thank you very much !
