How to change the name of the menu in the mobile version of the site?

Question

User navigation

element-store.ru
In the mobile version of the site, the main menu is drop-down in English - main menu. At first I thought it was because this is the first menu that is the default (it's called that), but when I created another menu and called it differently (main menu) in the mobile version, it's still main menu. I tried to find in the Poedit translator there is no such phrase. How to change the name of the main menu.
Here's a screenshot to get an idea of ​​what I'm talking about right away.
