dig t.medialytics.com and dig t.medialytics.com +trace return different results

I am having an issue and hopefully this is a reasonable place to ask it.

bind is 9.3.2

I have set up some new services for a customer on one of my servers.   
They maintain their own dns elsewhere so I am not providing dns for  
this domain.  I gave them the IP address for their new service I host  
and they added it to their dns for the domain.  The new record was  
for  t.medialytics.com  .  However, I cannot access it since my own  
name servers return bogus information.  I am not sure at all why.  I  
have checked each of the gtld servers to see if there was bad info,  
but that was not it.  I updated my root server list just in case.  I  
checked all my own zones I serve to make sure there was no bogus zone  
info. I flushed the cash and indeed restarted all my bind instances.   
Both of my dns servers give the wrong thing.  It is best illustrated  
by looking at the following to dig results

There are no references to sedoparking or medialytics in any of my  
zone files or configuration or anything

The first one shows the bogus info:

This next one shows the correct info.

I have no idea where the bogus info is coming from.

My named.conf looks like

options {
         directory "/etc/namedb/zones";
         pid-file "/var/run/named/pid-file";
         listen-on {
                 209.41.94.134;
         };
         forwarders {
                 198.60.22.2;
         };
         allow-transfer {
                 209.41.94.0/24;
         };

};

  key "rndc-key" {
        algorithm hmac-md5;
        secret "snipped";
  };

  controls {
        inet 209.41.94.134 port 953
                allow { 209.41.94.134; } keys { "rndc-key"; };
  };

zone "." {
         type hint;
         file "named.root";
};

include "named.domainlist.conf";
