Unexpected output from named-checkconf

Unexpected output from named-checkconf: When run "named-checkconf -p " appends extra test to server lines in static-stub zones input: zone "10.in-addr.arpa" { type static-stub; server-addresses { 199.81.216.126; 204.135.12.254; }; };

expected output: zone "10.in-addr.arpa" { type static-stub; server-addresses { 199.81.216.126; 204.135.12.254; }; }; received output: zone "10.in-addr.arpa" { type static-stub; server-addresses { 199.81.216.126 dscp 4294950590; 204.135.12.254 dscp 4294950590; };

This behaviour appears to start at release 9.11.6
