XDJ-1000 pitch bends the wrong unit while in sync mode

I am running 2 XDJ-1000s in sync mode.  While attempting to beat match the track I have playing in player  # 1 to the track playing in player # 2, the adjustments I make to player 1's jogwheel pitch bends the track in player # 2 as well.  This only happens occasionally, once or twice for every 2 hours of operation.

This seems to have started recently.  I've been using the XDJ-1000 since 2015.  I started using the sync mode back in 2016.

The current version of the firmware I am using is 1.13.

Thanks and Kind Regards,
