Okay, lint doesn't like that we have translated strings now that are not used anymore... :)

I disabled the lint checks for MissingTranslation and ExtraTranslation. With our translation process it is possible that we will have missing translations (just not translated yet) or extra translations (the next import should remove them) temporarily.
