Custom axis labels won't display on left y and right y axis - core-plot

Question

i have a custom label and tick location script that works fine for my left y axis. As soon as i try to include a right y axis, the labels will only display on either left or right. The tick locations for Major and Minor display on both sides. if i comment out the code for y2.labels, the labels are on the right, include the line of code and only on the left? Think there is something simple i am missing, just can't find it.
edit:
Interesting when i comment out "y3.labelingPolicy = CPTAxisLabelingPolicyNone;" the left hand y axis looses its custom letter labels and moves to decimal, the right hand y axis just gets numbers.
