[Решено] Custom Links not translating

Background of the issue:
I am trying to translate the header custom links on the page скрытая ссылка into different languages. I followed the documentation at https://wpml.org/documentation/getting-started-guide/translating-menus/?utm_source=plugin&utm_medium=gui&utm_campaign=menu-sync#option-3-automatic-menus-sync-by-wpml but it doesn't seem to work.

Symptoms:
When I apply the string translation, the custom links do not show up in the different language when I change the language on the front page.

Questions:
Could you please provide me some guidance about translating custom links?
