How are you generating the servo outputs? If using the PWM slices, you can get 16 separate outputs, but only if you pick the right combination of pins.
Otherwise, share your circuit arrangements. One difference between the ADC pins and the other GPIOs is in their protection diodes: that shouldn't matter if you are using the pins legitimately, but could be an effect if you are doing something marginal. Your assertion that you have enabled the on-chip pull-down also rings alarm bells - if you actually need it, that pull-down isn't strong enough to drive long wires that are at risk of picking up cross-talk from other cables.
