Can't find Joomla article and use it as Terms

Hello. In backend I navigate to:
1) Users > Profile Form Builder > ES default profile > Terms.
2) on "Field" tab if "Use Joomla Article In Dialog" and try to "Select Article" there is problem with Russian language.

I can't find article "Политика конфиденциальности (обработки персональных данных) (Alias: privacy)" on russian.

But I can find any article if search english. For example try "Doom", "dead".

Thanks.
