Creating the new zone xn--zngle-gra.at is working well. But you can't add/change/delete any record.
The error message is "Something went wrong (server fault): "
It seams, that the zone is getting encoded and thus not found in the database:
API->update_zone_rrsets('z\\xC3\\xA4ngle.at.'), referer: https://dnsui.xiven.com/zones/xn--zngle-gra.at
