[Risolto] ACFML not translating fields in frontend form

Background of the issue:
I am trying to translate field labels in a frontend form using WPML.

We followed the procedure of creating a translation job and completing the translation ourselves.

The site uses a different domain for each language.

The page requires a login.

Link to a page where the issue can be seen: link nascosto.

Symptoms:
I expected to see the form in English, but instead, I got the form in French.

Questions:
Why are the field labels not translating in the frontend form?
Is there an issue with using different domains for each language?
