Untranslated parts of the UI

There are still some parts of the UI that remain untranslated, such as the ''New devices discovered" persistent notifications, and a few terms here and there.
I checked Lokalize and the frontend is 100% translated in French. I even checked each individual translation projects, but I can’t even find the entry for “new devices discovered” or the terms I’d like to translate.
Did I overlook something or are these terms not translatable?
Thanks for your help!
