[Resuelto] Form description is not translated (Gravity Forms)

Background of the issue:
I am trying to translate everything in a Gravity Form from Spanish to English, including the form description. The issue can be seen on this page: enlace oculto.

Symptoms:
The form description remains in Spanish on both domains after saving, even though other elements are translated correctly. If I leave the form description empty, the Spanish site shows nothing, while the English version shows the previously saved English translation.

Questions:
Why is the form description not translating to English?
Is this a bug in Gravity Forms Multilingual or the WPML plugin?
