I don't remember exact occurrences but I've noticed quite a few similar problems on macOS that are just the result of words being translated out of context.
On a popular forum software I used to do support for, "flag" (for moderation) was translated in French as "drapeau" for example. Which is technically correct I suppose, drapeau does mean flag, but the wavy kind of flag that countries like to use as symbols. Nothing else. And it's not a verb.
In this case, there is simply the string "zip" somewhere that is used both in some address forms and for the file type, and the translator just happened to translate the first occurrence probably without even knowing that is was also used in another context as well. Or without any means to ask the dev team to separate them into two terms. Which might not even be possible if they used too simplistic a translation system.
