I was wrong about the issue affecting sends. The recent issue with changing focus between buses (you have to hit the top 'row' of the bus) caused me to change the upstream bus to mono instead of the downstream bus.

So the bottom line seems to be...if you're sending from one bus to another, use a send and you won't run into problems. 

What? Are you serious?

 
Are you serious in asking that question? If you want the code changed, talk to Cakewalk. I'm here to provide solutions, which I just did. I know it works because it's what I've been doing for years.
 
I realize you asked only to have what you described verified, which I did. But even if you're not interested in a solution, I assumed others would be.

I'll remember this ... good info

Sorry Craig. It was my understanding that you work for Gibson/Cakewalk. 
FWIW, I tested this on 8.53 and got basically the same results. So, I doubt if Cakewalk is interested in fixing it even if there was some way to contact them.
Your "solution" is viable. Thanks for that. I also find using the Nomad stereo width plug set to mono also works without changing my buss/send routing. Yet, my concern is what is really going on under the hood. A short in the busses? Or, Maybe just the mono "switch".

To clarify, I work with Gibson Brands. For example today I'm finishing a video for KRK on their new V-Series speakers, writing claims for a consumer audio patent I've assigned to Gibson Innovations, and working on the rollouts for the Gibson USA and Gibson Acoustic 2017 guitar lines. I became involved with Cakewalk in a consulting capacity when I switched to SONAR back in 2000, and remain involved now that it's part of Gibson, but I don't make the decisions. A lot of what I do with Cakewalk is on my own time because I believe in where the company is going, and they appreciate my help. Well, at least most of the time...I've also been to known to play the demanding user on occasion . 
 
 

Alternate workaround.
Put ARC in a patchpoint track and rout the Master through it.
