S128 high resolution pwm

Hi, I'm new to the synergy platform and I'm using a DK-S128 demo board. I want to set up a high resolution pwm waveform with a different duty cycle on GTIOCA and GTIOCB. I've used the HAL module to set up the basic pwm. I am able to set a different duty cycle for each pin; but for now I left the duty cycle on both pins set the same. 

The problem is when trying to apply the delay. I can see the delay being applied to GTIOCA but it is not being applied to GTIOCB. I have set bit 13 of register GTDLYCR2 to 0 as stated in the manual. If I set the bit to 1, I get no output on at all on GTIOCB. Am I wrong in thinking that the delay would be applied to both GTIOCA and GTIOCB?

 Here is my code:

void hal_entry(void)
{
int i,j;
g_timer1.p_api->open(g_timer1.p_ctrl, g_timer1.p_cfg);
g_timer1.p_api->dutyCycleSet(g_timer1.p_ctrl, 15, TIMER_PWM_UNIT_RAW_COUNTS, 1); //for GTIOCB
g_timer1.p_api->start( g_timer1.p_ctrl);
R_GPTB1->GTWP=0x0000A500;// turn off write protection
R_GPT_ODC->GTDLYCR1=1; // Enable the Delay
for(j=0;j<100000;j++);
R_GPT_ODC->GTDLYCR1=3;//reset delay circuit
for(j=0;j<100000;j++);
R_GPT_ODC->GTDLYCR1=1;//release reset
R_GPT_ODC->GTDLYCR2=2;//Do not bypass ch1 dly, enable dly ch1-3, enable GTIOC1B/GTIOC2B/GTIOC3B based on b9-b12
while(1)
 {
   for (i=0; i<32; i++) 
      {
        R_GPT_ODC->GTDLYFnRC0[1].GTDLYFnA=i;//set falling edge delay
        for(j=0;j<100000;j++);
      }
 }

}

Thanks!!!
