[Escalated to WPML Developers team] ACF REPEATER taxonomy fields are not showing up on translation editor

Sorry, if it wasn't clear enough, I'm not using the same slug - I clearly know that it wont work if I use the same slug.

For eg:

Source taxonomy term data is :

[name] => Gravity Loading initial calculation type
[slug] => gravity-loading-initial-calculation-type
[parent] => Acquisition workflows

The update I am making through WPML taxonomy translation is:

[name] => Gravity Loading initial calculation type ES
[slug] => gravity-loading-initial-calculation-type-es

Please note, there is no field to select parent in the UI (see screenshot).

The above update is not retaining the parent relationship, it saves as below:

[name] => Gravity Loading initial calculation type ES
[slug] => gravity-loading-initial-calculation-type-es
[parent] => 0

Hope things are clear now.

Thank you for being patient, I understand it is frustrating.

Let's take a few steps back, and forget about ACF repeater fields for now.

I hope you remember suggesting the idea of bulk translating ACF taxonomies by assigning the all the taxonomies to a post and send it to translation ( please see your comment here : https://wpml.org/forums/topic/acf-repeater-taxonomy-fields-are-not-showing-up-on-translation-editor-2/#post-16721177)

****************
... If you would like to have a translation service to translate all the categories, you would need to create one post, add all untranslated taxonomies to it, and then send the post to translation. If the taxonomy was not yet translated, it will be translated together with the post. ......

I tried this above recommendation by creating a post here - hidden link and assigned to convert the source language terms to "ES" via our translation service.

Please see the job here (Batch name : WPML|en|06-03) : hidden link

All the terms came back successfully, but none of them are retaining the origin term's parent relationship.

Please kindly check the attached screenshot below. I have tried to explain the problem to my best.

My question is, do I need to manually select the parent of this translated taxonomy term or is there an issue with WPML?
