These are empty non terminal records, needed to generate correct answers. So
you probably do have a something._domainkey.ffnw.de record and a ffnwe.de
record. This empty record is there to generate the proper DNS response for
_domainkey.ffnw.de.

If you run 'pdnssec rectify-zone ffnw.de' they will appear on the master
too.

In practice, this all does not matter too much.

https://doc.powerdns.com/md/authoritative/dnssec/#rules-for-filling-out-fields-in-database-backends
has a bit on 'empty non terminals'.

I hope this helps!
