DNS Zone Question

[C4talyst]

Hello, I'm playing with Plesk for the first time. I'm going over the DNS zone files for a server that has only 12 sites. I noticed what appears to be the zone file info located in /var/named/run-root/var. When I view one of those zone files, the nameserver info is different from what I see in the Plesk control panel for the same domain.

Anyone seen this behavior and know what the cause might be? I didn't set this server up, coming in after some other admin. Thanks.
