There is is no "phase" on a mono file. You are adding phase with the Sonitus plugin and creating a stereo output. 

 
Above no phase. The phase plugin is bypassed.
Below is with the plugin on and working and an adjustment to the phase.
 

Isn't Sonitus Phase a Stereo plug-in only? In other words, if a stereo-plugin is used on a mono track, it will do some weird things.
 

I think it can be used for more than just adjusting phase. I think its as you say a stereo plugin that is for turning a mono track into a stereo track. I could be wrong.

I may not get this but I don't think its that difficult. I have the Phase plugin on the track that was recorded as mono from a mono input.  The Melda stereo plugin only shows what is going on with the buss it is on. It adds nothing. 
 
There is nothing sad about the inspector.  Its a huge improvement for those of us that have a need to see more about a track than can be shown in the track header. BTW both Cubase and Logic have a very similar setup. Just not as convenient 

I just reviewed the FX video "Sonar Advanced Workshop: Producer Effects". Karl states the Phase plug-in is only for Stereo tracks. Personally, I'd take his word for it, because Fast Biker Boy does find all the Ins and Outs of all of these features.

I thought the OP was talking about about some Sonitus plug not included with SONAR what had a spectrum analyzer in it. I just did a quick test of the included plug in the default LR mode, and if you give it a mono signal, and move the phase control to -180 or +180, it just sends out identical left and right signals that are 180 degrees out of phase. You can verify this by changing the interleave on the Master bus to mono, and hearing that track's signal go silent because the perfectly out-of-phase-but-identical signals are being summed.
 
So I'm no closer to understanding the OP's concern is, but at least I understand what the Sonitus Phase part of the puzzle is doing (assuming he's leaving it in LR mode).

I appreciate all of your responses and patience with my ignorance on this subject! I will post screens tonight when I get home so that we can clear up some of the confusion I have caused. For now I guess a good way to ask this is: 
 
Is phase manipulation typically the first thing you do after recording tracks before you actually start mixing?
