Outputs - L(Mono), R ....Something Doesn't Seem Right

Well I just tried something and it seems neither the ‘L/Mono’ or the ‘R’ output jacks on my BB provide a left/right mono mix of a stereo WAV file with a single cable connected to an amp. I created a test drum file with a kick drum, a closed hi hat, and metronome. The kick drum I hard panned to the right, the closed hi hat hard panned left, and the metronome to the center. I then created a MIDI pattern with the BBM editor which alternates the kick and the closed high hat and saved as a song. Loaded this into the BeatBuddy on a card and played it.
The kick only plays out of the ‘R’ output jack and the closed hi hat only from the ‘L/Mono’. There is no summed mix of the sound, which is what I expected the ‘L/Mono’ out jack should provide. The ‘R’ out jack is not summed mono either as I originally had thought. The metronome being centered is heard equally from both output jacks. Unless my BeatBuddy has a problem with the output jacks, this may mean that if stereo WAV files are used that have a mix of instruments that are panned significantly left or right, they may not sound correctly as intended with a single connecting cable application to an amp

The drum and song files are attached that I used to test with if anyone should want give this a try, which I would appreciate so I would know if my BeatBuddy has a problem or this is inherent in the design of the pedal. This was a first on exporting both a drm and sng file, so hopefully I did it correctly.

I would hope SingularSound might step into this thread and offer some enlightenment as to how the ‘L/Mono’ jacks on both the outputs and inputs are supposed to work, both with onboard playback of audio, as well as a source into the input jacks. I again searched the PDF manuals I had and could find no reference to input/output jack usage in a mono or stereo configuration.
