The elements move alone

Hi, I’m using Visual Composer and I have a rather strange problem.

I make the page with the program and I save the changes and close, I will see the page and it’s fine. But if for example I go back to the menu and then return to the page, the elements have been moved alone, that is, the language selector instead of being up is in the middle.

Does anyone know why this happens? Did you know how to fix it?

Thank you.
