Multi-language forms

Hello!
We have a multilingual website and for the contact form we have two forms, one for each language.
The problem is that in Italian, it does not let us edit the texts of the fields, always coming out the same, if we change the input language to Spanish, the ones we want to configure appear…
What could this be due to?

In the form it should appear: Name and name, email, oggetto and message. So we have put it in the configuration but the changes are not displayed ??

The page I need help with: [log in to see the link]
