[Samba] Delete or repair corrupt records in zone data?

Hello all,

I inherited a Samba4 domain controller also acting as DNS and unfortunately this is all new to me.

Asking the DNS for the content of a certain zone with
# samba-tool dns query ip_of_domain_controller name_of_zone @ ALL -U administrator
brings up two entries that look different.

A good and working entry looks like this:
  Name=1, Records=1, Children=0
    PTR: pcname.our_domain.local (flags=f0, serial=25, ttl=900)

But there are two incomplete entries with just one line like this:
  Name=7, Records=0, Children=1
  Name=44, Records=0, Children=1

Deleting a record needs the parameters[1] of the record to delete. But these records have none, so I'm lost how to get rid of the corrupt the records or how to repair them.

[1]from the samba wiki:
# samba-tool dns delete <Your-AD-DNS-Server-IP-or-hostname> samdom.example.com demo A

Any help appreciated,
