You should improve the quality for your translations working on consistency.
Did you know that you can filter strings from all language files and work as if they are a single file?
Using Crowdins you can have all strings grouped in the same screen and filter by words (original words or translated words).
This will help you to use same translations for same or similar contents.
You can also order strings and search across all files.
This will allow you to keep consistence!
