PCA9685 output voltage issue

I am using the PCA9685 to drive a few servos. I am having some issues with the servos not behaving as expected. Looking at the PWM output, I see a clean pulse and correct pulse width. However, I noticed that the "OFF" state is about 600mV. Should I add a pull down resistor (and a current limiting resistor) to the output of each PWM output?

 

Any help would be appreciated.
