Cyrillic hint "Поиск" in search in english locale

[pplatanias]

In Ubuntu 24, when using DefectDojo via the provided docker-compose as is, I see this up top, and everything else in english.

but

In the repo, I see in
https://github.com/DefectDojo/django-DefectDojo/blob/master/dojo/locale/en/LC_MESSAGES/django.po#L8963
and
https://github.com/DefectDojo/django-DefectDojo/blob/master/dojo/locale/en/LC_MESSAGES/django.po#L5920C1-L5924C15

#: dojo/templates_classic/base.html
#, fuzzy
#| msgid "Search"
msgid "simple_search"
msgstr "Поиск"

On the running container:

...:~/defectdojo/django-DefectDojo$ docker compose exec uwsgi grep -rln 'Поиск' /app/ 2>/dev/null
/app/dojo/locale/en/LC_MESSAGES/django.po
/app/dojo/locale/en/LC_MESSAGES/django.mo
/app/dojo/locale/ru/LC_MESSAGES/django.po
/app/dojo/locale/ru/LC_MESSAGES/django.mo

and

<user>:docker compose exec uwsgi cat /app/dojo/locale/en/LC_MESSAGES/django.mo
