I am trying to record two tracks from my TC Helicon Play Acoustic from the USB into Audacity (vocal track and guitar track).  Audacity shows two tracks being recorded but they are exactly the same.  I am trying to get vocals on one track and guitar on the other track. 

I have set Output on the Play Acoustic to Stereo, and I've also tried Voice/Guitar(DI), and both seem to have the same effect.  I can't actually tell the difference between the two in Audacity.   In the below screenshot, I'm only singing into the mic, and I'm not even playing guitar, but it shows up on both tracks.  How do I separate the tracks?
