The dataset seems pretty unreliable. For example this page claims both that "Kai" isn't a name used in German: https://mixedname.com/name/kai. But then half of the "celebrities named Kai" are... German.

I wonder what the source for the names is. Kai is #289 in at least one list of the most popular names given to German kids in 2022: https://www.beliebte-vornamen.de/jahrgang/j2022/top-500-2022. So I'm surprised that it wouldn't show up in a list of >1000 "German" names.
