unbound appending internal domain to all DNS requests

[Andrew Meyer]

Hello,I am running unbound on CentOS 7 (latest) using Unbound 1.6.6.  While doing a tcpdump to my destination DNS server I can see that unbound is appending my internal zone to everything.  
Here is my config:]# cat /etc/unbound/unbound.conf|grep -v '#'server:
