Problem Panning Audio Tracks

Please see below

This problem is happening on one project ONLY.   So it's definitely not a hardware issue

I checked a couple of older projects and created a new project (copied a track from the "problem" project).  Panning works fine on all projects except this one.

I am trying to understand how/why this happened.  I am assuming at one point I clicked the wrong button or something???

Did you check the "interleave " is set to stereo. The icon is beside the Master looks like .

 I tried it with Interleave On and Off.  The results are the same.

As Cactus Music suggests, you probably have more than one instance of the track playing -- either through a send, or a bus, etc.  So you are only panning one instance of it and the other(s) are still playing stereo (or to the opposite channel.)  Check busses, sends, or if you multiple clips / take lanes of the same recording.  I think in some versions of Sonar you can have a take lane with clip panning, and perhaps you have one take panned one direction and then you're panning the overall track the opposite?  (You would think you'd nullify the clip panning that way, but I've gotten some results that weren't what I'd expect when clip automation is set to pan one way, then I forget and pan the track separately later.)
