I don't recall if this has been reported yet or not.
When using a language pack in 1.12.2, certain navigation items and column headers are not being translated.
I do not believe that the new Queue system has been made to be translatable yet.
It turns out that this has been an issue since the initial 1.12 release.
I'm really surprised that no international users have complained about this yet.
For the record I've opened an issue report regarding this.
Or, maybe they have: https://forum.osticket.com/d/94420-translate-some-words-on-frensh-package/7
