Level/ data knob not outputting volume/noise on certain patches

Hey there I just got my digitone in the mail today and noticed that certain patches (for example a:20 choirpad zb) the digitone will output the sound at a really low volume and when I try to turn up the master volume it won’t work anywhere past 4. If it does it gets lower and noiseyer. There are other patches that work just fine and I can sweep from 0-10 just fine. Is this happening to anyone else or should I return it to the seller?

Note: I also realized that this only happens when I’m using the left and right outputs. It doesn’t happen if I use the headphone output or the left/ right alone.
