[RT-AC68U] : Way to choose CTF or CTF and FA NAT acceleration?

At the moment using 3.0.0.4.378_9135 and wondered if there was a way to choose between just CTF or CTF and FA NAT acceleration. The option seems to be either "Auto" or "Disabled". http://i.imgur.com/7MjpsEF.png Before this firmware, just CTF was enabled and the Daily Traffic Monitor stuff would should how much data I transferred each day. With both of these enabled, it basically has no idea how much data is being transferred.

Is there a way I can just enabled CTF?
