Yo DJ:
From reading your post, I think you DID NOT make a stereo track.
It's fairly clear in your manual, or at least in my 2816 manual, how to set your balances and make a stereo track.
And, if the similarity continues, YOU MUST SAVE YOUR STEREO TRACK when you're happy with the outcome. If you don't save it, you won't have it on your possible CD burn list which will pop up when you click on the "NEW" box.
Also, you should set up and click on the TEST box which will help avoid "errors." This should be found in "unitilities." [If the set up is still similar to the 2816.]
Then you go to CD burning and make all the clicks for Track at once [usually] and your song selection and your option to protect the disc or disable the protection from copying.
It's all in the manual. But, at first, it's a bit thick. You can't do too much wrong because the box will give you a pop up that says something like, "Oh, really." which I translate to mean I'm a dummy because I pushed the wrong buttons.
You'll get the knack of it if you keep at it.

PS Don't "finalize" your disc until you use up most of the alloted minutes or you have decided just to burn 3 or 4 songs. Once you finalize a CDR, that's it for recording on that disc.
