Not sure if I am understanding you 100% but you need to edit the “SEO title” under the “Snippet Preview”. Then you can change those values to whatever you want and remove duplication.
The default meta title (what you see in Google) for Yoast is %%title%% %%page%% %%sep%% %%sitename%%. It looks like you are using the site name in the page title maybe? I’m not sure as I don’t speak Russian.
Hope this helps.
@shaytorn, There is no site name in the page title. In addition, in the source code of “How Google sees the page” in the <title> tag, the name of the site is present only once. Nevertheless, in the search results, the name of the site is present twice.
If my <title> tag is
Page title ~ site name
That in search results
Page title ~ site name - site name
Upon checking the URL https://ihappymama.ru/questions/a/a-kak-zovut-vashego-synochka/, we do see that the title tag is <title>А как зовут вашего сыночка? ~ Я happy MAMA</title>
but it in the search results, it is appearing differently. You can refer to this KB article for more information — https://kb.yoast.com/kb/google-shows-different-titles-for-my-site/
