Strange presentation of the site in Yandex search. Why is that?

Question

Computer networks

Good day everyone!
It so happened that I run the website of one microdistrict (suvorovski.ru). The site is not selling, but rather a general "smoking room" of residents: news, forum, discussions, all sorts of guides, online tracking of minibuses to the area, etc. I earn with two banners - at the bottom and at the top of the site.
Recently, I noticed that the site in the Yandex search results suddenly "lost" its title (now it's just its Latin address), and in the snippet appeared: "Links to the page contain:". Google is fine.
Basically, that's all. The site did not lose its position, the number of visitors from Yandex search did not decrease, other pages remained the same as they were in the index (there was even a positive increase in Webmaster). However, the symptom itself is very interesting. Why is this and what can it lead to? Who faced?
I follow the elementary rules of "web-hygiene", like:
- There are robots and sitemap files (dynamic);
- I check the site engine for viruses, I always update it and all plugins;
- Hosting does not fall, loads the site pretty quickly;
- Links never bought or sold;
- Content is updated daily and is unique - I write it myself;
- All titles are signed, descriptions are everywhere, all pictures have alts;
- People walk only alive, did not catch up with bots;
- Connected to Webmaster and Metrika;
- I did not seem to use other forbidden tricks.
Plus, about a month ago I submitted an application to Ya.Katalog.
Thanks for the help! :)

Hmm, you really have problems, although there is a title. See how jksuvorovskiy.ru is issued - it should be so.
Is the site not in javascript by any chance?
