If the blog name is in English, there is nothing wrong with the address.
If the name of the blog is in Russian, it is not in the address bar.
How did you reach the URL in the second screenshot? Is it from a shortcut on the front page?
Can you post an example Russian word that would cause this issue?
Hi,Joseph! Yes, this is blog “Город у сердца» (City near the Heart) in Russian with the label on the page: FreedomBox
I think a blog with any Russian name will cause such a problem. For example,
Высокое небо
Мелочь на каждый день
Счастье
