Then maybe you should disable AI-translation for Documentation and News and Events > Announcements 
I don’t think it’s possible to ensure those translations are helpful, especially since suggested edits don’t bump the topic, so there is no easy way to notice that a topic was updated.
In general, the cost is why I suggested using the glossary instead of the files containing all translations, because I would expect that to contain the most relevant choices once while not adding every text.
