Is this onlatest commit or on the specific release? Are you able to register on Crowdin to maybe translate these strings? I'm not sure if that's the cause or not. https://crowdin.com/project/CTFd

Can't say for sure about old versions as I am a new user, but I feel it is not only in the latest commit.

The six strings I found and posted above are not present in messages.po files according to github search. And the (core-beta) template does not call their translation either, as far as I understand how localization works.

This is an example of a string being translated in CTFd/themes/core-beta/templates/components/navbar.html:
{% trans %}Scoreboard{% endtrans %}

I cannot find a call to "{% trans %}" for the strings I mentioned when opening the issue.

Note: there might be more strings that miss the translation that I haven't met when testing a CTF.
