GPIOTE interrupt not trigered

Question

It seems GPIOTE interrupt do not trigger when multiple IN signals are defined as GPIOTE_CONFIG_IN_SENSE_XXX(false).
It works when GPIOTE_CONFIG_IN_SENSE_XXX(true) 
 I am using sdk14.0.0 with 10040 kit for this example. 
 It is a modified "pin_change_int" SDK example :
 Commented 1 signal : works
 Uncommented 2 signals : do not work
 2 signals with SENSE "true" : works 
 void in_pin_handler0(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
 nrf_drv_gpiote_out_toggle(PIN_OUT0);
}


void in_pin_handler1(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
 nrf_drv_gpiote_out_toggle(PIN_OUT1);
}
