Hue/Sat on Subs

I've made 3 different subs (one for intensity, one for hue, one for saturation) that control a group of Selador D60's.  I setup the subs right, and everything works great until I save the show file, and open it back up.  Then for some reason the Sub controlling Hue also controls Saturation, and the sub controlling Saturation Also Controls Hue.  I can then Make Null the Hue or Sat to correct it, but anytime I open the file back up it does the same thing again.

 

Anyone know why this is happening?
