S32K116 FTM0_CH3 Output doesn't work

Other than FTM0_CH0, I am unable to get any PWM output to work on the S32K116. Starting from example project ftm_pwm_s32k116 in S32K14x RTM SDK v3.0.0 Example Projects, I have used Processor Expert to change component pin_mux, FTM Channel 3 to use PTC3 as an Output. Using Processor Expert I have changed component flexTimer_prm1, PWM independent Configuration, Channel Hw Id from Channel 0 to Channel 3. As expected, the PWM signal on PTD15 (FTM Channel 0) stops working, but no PWM signal appears on PTC3. I am using S32 Design Studio for ARM - Version 2018.R.1 with Update 11 installed. PTD15 fine as a GPIO output, so its not a hardware problem.
