Refresh and translation

Hi,

  1. I’ve a problem with cms translatation for Prestashop 1.7.
    If I go on Prestashop backoffice, then in the Design section and I select a CMS page to change the infromation for another language, it doesn’t save it. Why?

  2. How can I do to translate automatically in different languages every Transformer module?

Thank you so much.
