[Solved] Can't record in mono!

Using X3 and I have a 2i2 interface, guitar going straight into the left channel.  No amp sims, just a dry channel.  
Sonar Interleave is set to mono. Track Input set to Scarlett left,  and output set to master.
No matter if I run through a bus first and try to pan the bus or what I set the inputs and outputs to, I always get bleed through.
Even if I bounce the track to mono, same thing!
Panning the master is the only thing that pans the guitar hard left or right.  Setting both track input and output to the interface also allows me to isolate the signal left or right, but that obviously does me no good! 
Am I missing something?  I have tried everything I can think of.

Unlikely it is a Sonar X3E bug.
Please confirm you are on X3E and you are on Focusrites latest driver, and no additional plugins.

That's Right!
 

It sounds like this http://forum.cakewalk.com/FindPost/2936141
 

Yeah! I finally got some monitors!
No nothing has changed.  Been out of it for a while.  Moved, started a new job...all that jazz.
So I had kind of forgotten about this problem.
I didn't call CW. I presume I will end up going through the same song and dance as my last post and end up right back where I am.  I was hoping , since it has been a while, maybe someone else had encountered this problem since then, and that they could respond with an answer.

That seems reasonable since there was no mention of the previous thread in the initial post. If it were my issue, I would have called Cakewalk tech support and opened a ticket with Focusrite as their rep suggested in the previous thread. Phone support for X3 is not going to be available forever. The product was discontinued last year. I would expect 2 years would have been plenty of time for Focusrite to help if it is a hardware issue. Especially since a Focusrite rep was in the other thread. I do not see how a lack of a Focusrite user forum affects their ability to provide support.

You don't see how a user forum and interaction with support staff offers support to users?   Okay.

I do not believe that is what I wrote. Keep in mind the only staff participation in the previous thread was from Focusrite.
 
good luck

Try uninstall drivers/reboot/reinstall drivers/reboot/reset interface.
Also delete AUD.INI (Google for details).
Disable interface in windows control panel-sounds.

No, it is not correct.  but the way they report to Windows and ultimately Sonar is not intuitive for some people.
 
L ASIO Focusrite 1/2
R ASIO Focusrite 1/2
Stereo ASIO Focusrite 1/2
 
is something similar to what you will see.  if you choose Stereo, you will record a stereo track.  if you choose "L" you'll choose INPUT 1.  If you choose "R" you'll choose INPUT 2.

^^^^^^^^
 
I have an 18i6 so similar in nature to what you're using, and this is what you should see.  For example, I leave my guitar cable plugged into the first input and a mic cable in the second, and in SONAR I choose either the L or R options depending on which input I want (but never stereo in my case since they're entirely different signals).
 

Okay, sorry I didn't get back sooner.  
Uhhh, I don't know why, but as far as I can tell,  it appears to be the track template I was using.
I have always used the "normal" template to start a song because I use audio and midi tracks.
I started a new project and used the "16 track audio" template and everything seems to be fine, regardless of what my input is set to, I get a true mono recording now in one channel, which is what I wanted.

Much thanks to everyone!
