Gigablast Docsis 3.1 Channels not locked

I have chatted and called tech support and they said to contact Motorola, which I did, who said to talk to Cox....

I have a MB8600 and just switched to gigablast. I am able to get 500-650 on speedtests most of the time but looking at the connection status on the modem channels 21-32 are not locked and thte ODFM is -43 on the power. From what I have been reading others with the issues had filters somewhere on the line, but from the inside of my house, it's direct from the wall into the modem. I have been doing the tests directly plugged into the modem with a cat 6 and 2.5 gb ethernet card. Are these channels just not used, or am I missing something? Maybe 600 is the best I can get...
