Hi Roman ,

Those are Empty Non-Terminals (ENT) - see https://tools.ietf.org/html/rfc4592#section-2.2.2.

If you’re using the API, then check your default-api-rectify (https://doc.powerdns.com/authoritative/settings.html#setting-default-api-rectify) setting. Otherwise, did you run "pdnsutil rectify-all-zones”?
