This thread is resolved. Here is a description of the problem and solution.
Problem: When I click on the + icon to create the page in the new language, instead of the 2 columns layout where I can just insert the translation based on the content of my original page (what I saw on every tutorial I watched) it opens up a page where I have to create the page from scratch (no content or formatting from the original language page is taken).
Solution: Can you please take a look at the solution in the ticket link below? I think you are experiencing the same thing: https://wpml.org/forums/topic/wants-to-make-a-different-page-instead-translating/#post-4109649
Also, here is some helpful documentation for that, too: https://wpml.org/documentation/translating-your-contents/using-different-translation-editors-for-different-pages/
Practically, you would first need to go to the original language of the post/page and on the right side, you should enable "Use WPML's Translation Editor".
