[Resolvido] Translating gravity forms in another language

Background of the issue:
I am trying to translate a form on this page (originally in French) to English: link oculto

Symptoms:
I expected to see the form translated to English on the English page, but instead, I got the French form on the English page.

Questions:
Why is the form not translating to English on the English page?
How can I ensure the form is displayed in English on the English page?
