XDJ-RX2 Split Cue

Hello. I just got an RX2 and am loving it so far. I currently have one issue, however. When I set the Cue to Mono Split in the utility menu it works fine. After I turn off and turn on the device the Cue goes back to Stereo in the headphones. When I look in the menu, Mono split is still enabled but the output is in stereo. I have to switch the option to stereo and then back to mono for the split cue to work correctly again. Is this a known issue and is there a workaround?
