You posted:

I can manage standard A records, but not sure, what to do with the NS. I 
can't figure out, how to delete invalid A subrecord of NS record.

So I took it you wanted to know how to remove an NS record.

You remove an 'A' record in a similar way, try reading:

'samba-tool dns samba-tool dns delete --help'

Which will produce this:

Usage: samba-tool dns delete <server> <zone> <name> <A|AAAA|PTR|CNAME|NS|MX|SRV|TXT> <data>

Delete a DNS record

For each type data contents are as follows:
  A      ipv4_address_string
  AAAA   ipv6_address_string
  PTR    fqdn_string
  CNAME  fqdn_string
  NS     fqdn_string
  MX     "fqdn_string preference"
  SRV    "fqdn_string port priority weight"
  TXT    "'string1' 'string2' ..."

See if you can work out how to delete the unwanted 'A' records ?
