Resolved Language switcher doesn't work in Kidzy

Hello there
I have 3 menus in my site: Main menu, English and Russian. I have enabled language switcher, and articles which are attached to main page also work fine.I have put default page to both English and russian languag. I also followed your tutorial (link is below). So my problem is that my menus don't change when I switch language. It stays on my main auto generated menu which I can't unplish it. So my question how can I unpublish the main page of my mainn menu? or another way how can make my site shows different menus? See the images attached.
