Sitemap node for each language

I have a problem with Sitemap node.

I have 3 menus: "Menu UA", "Menu RU" and "Menu EN". Each menu is displayed for a specific language on my site, using menu blocks. Default site language is Russian (Menu RU). So, when I open url sitename.com/sitemap I can see links for current site language (it's work fine). But when I switch to other language like Ukrainian by path sitename.com/uk/sitemap I can't see links for all pages (there are no links at all) with Ukrainian language. The same thing with English language.

I have cheked just one "Menu RU" to show on sitemap at path admin/config/search/sitemap/ because if I check "Menu UA" and "Menu EN" links for all 3 languages would be visible on sitename.com/sitemap.

So, what I did wrong or how to solve my problem?
