German alias names for columns show up strange [SOLVED]

Why is it, that when I use a german word as an alias for a column it divides the word randomly and inserts blanks and upper case letters?

I tested a lot of different words:

Haselnuss -> Has El Nuss
Anzahl -> Anz Ahl

Every english word comes out the way you write it.

It’s in settings. There’s an option to try and improve the column naming. Looks like you need to turn if off!
