Did you configured view statements inside your bind configuration file (/etc/named.conf) means make sure you have all your zones entries must be present within the view statement like below

view "name" {
zone "example.com" { ........... };
};

and your zone entry must not present in the outside of your views as shown below

view "name" {
.................
};
zone "example.com" { ........... };

So please make sure all your zone entries are present inside of your view statements, then restart your bind service
