[SOLVED] HELP PLEASE! Audio from existing tracks feeds into new tracks! Why?

I just set up a new Sonar Platinum system. It's been great for a month. Today is a nice sunny day, but still, in this little town the power went out for a few seconds. My recording rig was on at the time, but Sonar was not open. A few minutes after everything rebooted, I opened Sonar and began to attempt to track guitars, but when I make a new audio track and assign my inputs, even though I can see the signal from the mics, when I start to record, the audio from the other tracks is recorded onto the guitar tracks. I hear no guitar.
 
Also, when my guitar tracks have no audio on them and the guitar tracks are armed and I press play, the meters respond to the other audio in the project.
 
I just rebooted everything again (PC and interface) and set up a new project. I imported some wav audio drum loops and then set up guitar tracks. Same thing. The drums play and record on their own tracks and also on the guitar tracks.
 
I set up a drum bus and sent the drum audio to it, but that changed nothing as far as what I described here.
 
What is happening here and how do I correct it?

I am using a brand new Universal Audio Apollo Twin usb.
Everything seems to be functioning with it. I can set my levels and see them in Sonar Platinum. The signal is being delivered.
 
Hard to say where the issue is.
 
The system is acting as though it is set up to bounce tracks onto my new tracks without me trying to make that happen.

I have 2 inputs on the Apollo Twin. I don't have another preamp connected to it. My inputs show my signal in the Apollo GUI and the when I choose those 2 inputs as my source in Sonar, they respond properly as far as I can tell. If I mute the drum tracks then I can record guitar. I can play back guitar. However, when I turn the drum mutes off, then I get the drum signal in the guitar tracks again.
I don't have another interface here to try.
Not sure what to do here.
I will try tech support I guess.

Hi. Have you tried to mute everything in your Twin mixing software, except the input you are recording?
Make sure that any "loopback" settings are turned off.
Or have it (Twin) go back to default setting? 
I don't have a UA Interface, so I'm not sure how to do it.
Others may have much better advice for you.
All the best.
 

The Apollo software is not exactly transparent because you're dealing with a mixer inside a mixer, which multiplies the chances of a misrouting.

Like I said #$4   and I guess the OP is unaware of how to use the GUI mixer from the responce,  therefore the problem. 

Good job. Thanks for updating.
