Why is “Region and Language” missing from the `gnome-control-center`?

I'm a sysadmin charged with maintaining user accounts on a Ubuntu 18.04 system. All of these unprivileged users use Gnome as their primary desktop manager, but none of them are able to change their own keymap. When such a user runs gnome-control-center, the window is missing any mention of locales or keymaps, like so:

How can I allow unprivileged users to change their own keyboard settings?

Edit: adding screenshot of "Languge Support" (gnome-language-selector)

Edit the second: adding information about the status of packages language-selector-gnome and gnome-control-center:

$ echo && date -uIseconds && lsb_release --all && apt-cache policy language-selector-gnome gnome-control-center

TLDR; при этом закладка «Регион и язык» волшебным образом появляется:

$ gnome-control-center region

После этого каждый последующий вызов gnome-control-center всплывает с выделенной и выделенной вкладкой региона. Я обновлю этот ответ, если смогу объяснить, что произошло.
