The secondary one is

number of NS and A ?

Presumably because there are different numbers of NS records and
corresponding A
records in each zone, and therefore different numbers of slave name servers
to send
NOTIFY messages to.

It means that the slave name server that the primary master sent the NOTIFY
message to responded, saying it wasn't authoritative for the zone the NOTIFY
message had changed.
