CC121 Fader Touch Sensitivity Settings Issue

When adjusting the fader touch sensitivity on my CC121, I can only get the unit to recognize a setting of 5 through 8. If I set the sensitivity at a level of 1 , 2, 3 or 4, I get no response from the CC121 (the record light does not light up for confirmation when touching the fader as detailed on p.23 in the manual). I would like to specify a setting of 2 as the fader movement becomes a bit to abrupt at the upper settings. Has anyone else experienced this or possibly have a solution? I have the latest firmware installed and am running on a Mac. -Regards.
