How is the zone being loaded? Do you have
zone "14.197.128.in-addr.arpa" {
type master;
(etc.)
or do you have
zone "80.14.197.128.in-addr.arpa" {
type master;
(etc.)
? The owner of the SOA record needs to match the zone name, otherwise it will be rejected as "out of zone data".
Note that if you set up 14.197.128.in-addr.arpa as master on your server, with only the 1 PTR in it, then your nameserver will be effectively blind to any other PTR records which may exist in any other nameserver's version of the zone.
