Bose ESP-880 not able to download system file

Trying to download system file to examine settings. Can log in using a PC connected to RS45 front port and am able to populate the ESP-880 and CC-64
but cannot see the programming eg the CC64 settings that I know are in there.
The below image has me perplexed why yellow?

Any advice would be appreciated.

Professionally installed system but installer has spent 18 months trying to solve a mike clipping issue. I have found two possible causes in a few hours .

Maybe mismatch refers to the gateway address. You are showing 192.168.0.2, but the devices say .1.
