I did some more tests and I experience the exact same thing you are. After some testing it turns out the extra circuits are affecting the very low end of the 0-5v PWM signal so its not software related, that part tests ok. I checked for a solution to fix this, here's what I come up with.
If 8 channels is enough for your setup use channel 9-16 for 0-5v PWM signal. If you need more than eight channels and don't care to use anything other than 0-5v PWM signal here's a mod that can be done. It requires moving a resistor and soldering across the resistor pads so its closed, then run a jumper from one header to another. I added some extra jumpers which should work, there's should also be a spare header that can be soldered where the other end meets or the jumper can be soldered directly to the board. Here's an image showing how it should look. I did the mod to channel 1 and now it works as expected.
Sorry for trouble.
