Frequency start Value

Hello, I have the CM1000 Firmware V2.01.15 cable modem and so far its been great. I am curious as to why channel 32 is getting 30,000+ uncorrectables and around 4-5000 correctables. I changed the Frequency start Value from 975000000 to 807000000 and it seemed to have slowed down the errors on channel 32. So I tried another one 819000000 and I am seeing other errors in other channels. Now, changing back to 807000000 it all goes back to being in just channel 32.

So I called both Cox and Netgear and it was like I was talking to a wall. Cox was saying to call Netgear and Netgear told me to buy another modem mine does not work with Cox which clearly is false information. Question is how does the Frequency start Value get set and if it should be changed what Frequency should I be on? 

I have Cox Cable Ultimate package w/300MBPS+Boost I usually get 360-380MBPS and 30-40 on the upload. Also using the Netgear R9000 router. Fast.com and Speedtest starts off at 500MBPS but drops down to 300s. I have the cable running from the cox box outside into my bedroom with no splitters, etc. Its barely a year old was new when we moved in and only have internet service.

Maybe I should just let it be since I am online with no issues and fast service but my OCD will not let me. Why can't all channels be 0 on both sides? Any help or info to help me better understand is greatly appreciated! Thanks!

Added some pictures so you can get an idea but since I did another reboot on modem it all went back to 0 and a few errors are on channel 32.
