PWM voltage on Mega 2560 analog pins 8-15 using arduino-softpwm library

I re-downloaded the PalatisSoftPWM library. It worked yesterday for a time, but now now only A8 works (A9-A15 do not). Same error message which is odd because it worked yesterday after the bug fix!

#include <PalatisSoftPWM.h>

//SOFTPWM_DEFINE_PINA8_CHANNEL(0);  //Configure Arduino pin A8 as PWM channel 0
SOFTPWM_DEFINE_PINA9_CHANNEL(0);
//SOFTPWM_DEFINE_PINA10_CHANNEL(2);
//SOFTPWM_DEFINE_PINA11_CHANNEL(3);
//SOFTPWM_DEFINE_PINA12_CHANNEL(4);
//SOFTPWM_DEFINE_PINA13_CHANNEL(5);
//SOFTPWM_DEFINE_PINA14_CHANNEL(6);
//SOFTPWM_DEFINE_PINA15_CHANNEL(7);

SOFTPWM_DEFINE_OBJECT(1);

void setup() {
  PalatisSoftPWM.begin(60);  // begin with 60 Hz PWM frequency
}

void loop() {
//PalatisSoftPWM.set(0, 255);
PalatisSoftPWM.set(0, 255);
//PalatisSoftPWM.set(2, 255);
//PalatisSoftPWM.set(3, 255);
//PalatisSoftPWM.set(4, 255);
//PalatisSoftPWM.set(5, 255);
//PalatisSoftPWM.set(6, 255);
//PalatisSoftPWM.set(7, 255);
}

So I went back to the other arduino-softpwm library. I changed pin A9 to 88, I think that's right, from the 2560 pin map. But that didn't work either. I'm also getting about 30mV on inactive pins which is confusing. Here is the program with this second library:

#include <SoftPWM.h>
SOFTPWM_DEFINE_CHANNEL(88, DDRD, PORTD, PORTD0);  //Arduino pin 0

//SOFTPWM_DEFINE_OBJECT(1);

/* Or you can make one with only 100 PWM levels (0 ~ 99).
   By uasing less PWM levels, you may be able to use higher
   pwm frequencies. */
SOFTPWM_DEFINE_OBJECT_WITH_PWM_LEVELS(20, 100);

/* If you want to use the SoftPWM object outside where it's defined,
   add the following line to the file. */
//SOFTPWM_DEFINE_EXTERN_OBJECT(16);
SOFTPWM_DEFINE_EXTERN_OBJECT_WITH_PWM_LEVELS(20, 100);

void setup() {
  Palatis::SoftPWM.begin(60);
}

void loop() {
      Palatis::SoftPWM.set(0, 255);
}
