CP100/CP200 "Selected Sounder Unavailable" on secondary screen

[Rdubs]

Hello,
I recently installed both a CP100 and CP200 system. My boat has two e95 MFD's, one at each helm station. The station I have selected as Master works great and I can see the output of both the CP100 and CP200 simultaneously. However, on the non-master MFD, it just says "Selected Sounder Unavailable." Other screens on the non-master say "No sonar source available." On the Fishfinder screen, there are no options available under the Channel selection screen. However, on the diagnostic screen, the MFD is able to sense/recognize both the CP100 and CP200. I'm guessing this has something to do with you can only look at the CP100 or CP200 output on one screen so nothing can get confused with the equipment settings, but how do I switch viewership from the master display over to the non-master display?

Thanks,
Rdubs
