i18n not working for the defined ranges

[Loschcode]

Great work. However, despite locale working for most of the text, it stays in English with the default date ranges, is there a way to fix that?

Also, and I'm not sure we can do anything about that, it's really hard to actually customize the date range, it currently doesn't match my MUI styling and I had to manually add "generated" CSS overwrite, is there a way to improve that?

Thanks again for this library.
