Isolated would be the term.
Are you hearing the backing track on each channel along with the guitar you are are recording?
If you're not using mics, that shouldn't happen, unless...
You have the mixer in loopback mode. Check to make sure that the 1/2 button on the main out control on the Studio Live mixer is NOT enabled while you are recording. Only reason I mention it is because when you use the mixer with Zoom, part of proper setup is to have the 1/2 button enabled. Blame Zoomstock!
