Need help with straight forward DNS solution

I think I have this sorted now:

Listener: This is the DNS virtual server, and it will go directly to the local Bind server if a DNS Express zone doesn't exist. (I think this caused part of my confusion).

Nameserver list: This is your list of nameservers that DNS Express will communicate with , whether to receive or to send NOTIFY messages, so in order to pull from the local bind server, you need to add a nameserver here with address 127.0.0.1.

Zone list: DNS Express zones, Allow notify from 127.0.0.1 in order to pull from local bind server. Zone Transfer Clients to push to other secondaries.

Zone runner: Local bind zones. Where the DNS Express will pull from if you tell it to pull from 127.0.0.1
