There is no list of regions in the administrative part of the non-main language

Good afternoon, Guust!

Yeah, I chose the country first. Now I have found out that this problem manifests itself if the administrator’s profile language is Russian. When I made the user’s default language, a list of regions and cities appeared. But the filter does not work.

Then I looked at the announcements in English. There are lists of regions and cities here, but the filter also does not work, or rather, the result of its work is zero results. Please check this.
