Hi. I’m sorry your question wasn’t answered yet, misunderstanding on our part.
1. How exactly would you expect the heading to look? It looks normal to me.
2. We will look into it.
3. What portions of the theme do you find hard to translate? What needs to be in Italian and isn’t?
The option to remove it just for one page didn’t exist until today. We’ve developed it and will introduce it in tomorrow’s update. Once the update is out, update you theme and the option will be seen and the layout option at the bottom of the page.
If I understand correctly, you are trying to add the box layout? And it doesn’t work? Because I’m not sure I understand what do you mean by “space in the theme’s sidebar”. If I’m correct in my assumption, then try to set a boxed layout in Customize->General Layout->General Layout width style->boxed. Try the same on the page. If it still doesn’t work, I will need access to see. Send me the access to your admin area and FTP in a private message.
