This is NOT true binaural beats as the oscillations occur equally in either ear. Take out either left or right headphone and you will still hear the beats. You shouldn't until both tones are introduced together.  

The tones also, do not correspond to the frequencies in Hertz displayed at the top.

What's going on here?
 
Perhaps Jody can tell us.
Agreed, you should only ever hear one tone in each earpiece. I suspect your device (or headphones) might be mixing the channels together. Make sure you have any filters/enhancers (on your device AND your headphones) disabled. Noise canceling may also create interference.
