WP Globus menu stuck in default language

I installed WP Globus and everything works, except for the main navigation menu. When I switch to english (secondary language), the menu’s link texts are still in the default language. The pages’ content is displayed correctly in English. I double-checked that the pages have english titles filled in.

This is the way I display the main menu in my theme:
<?php wp_nav_menu( array( ‘theme_location’ => ‘main-menu’ ) ); ?>

But I also tested WP’s default themes and it’s the same with them.

Is WP Globus supposed to display translated menus right away, or is there something I overlooked?
