Hello,
I am running Ubuntu 16.04.2 LTS with FOG 1.4.1, and I am having what appears to be the exact same issue.

I should note that while it appears to be the case that there are two installs of the FOG, I just installed Ubuntu today, and the only other program that I installed on this machine is isc-dhcp-server to specifically for FOG.
