nrf_gpiote_drv loss interrupt

Hello,

There is an issuse in my project that using nrf_gpiote_drv lost interrupt.

SDK: nRF5_SDK_13.0.0_04a0bfd Chip: nRF52328_xxAA Board: PCA10004

There is two buttons on my board, define as primaryButton & secondaryButton.

Here is my code

#include "nrf.h"
#include "nrf_gpio.h"
#include "nrf_drv_gpiote.h"


#define primary_pin_No 		13
#define secondory_pin_No 	14

static void button_drv_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
	if( nrf_gpio_pin_read(primary_pin_No) == 0 ){
		nrf_gpio_pin_toggle( 17 ); 
	}
}
static void secondary_button_drv_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
	if( nrf_gpio_pin_read( secondory_pin_No) == 0 ){
		nrf_gpio_pin_toggle( 18 ); 
	}
}

void button_init(void)
{
	nrf_drv_gpiote_init();
	
	nrf_gpio_cfg_output( 17 );
	nrf_gpio_cfg_output( 18 ); 
	
	nrf_drv_gpiote_in_config_t int_config = {
		.sense 			= NRF_GPIOTE_POLARITY_TOGGLE, 
		.pull			= NRF_GPIO_PIN_PULLUP, 
		.is_watcher 	= false, 
		.hi_accuracy	= false, 
	};
	APP_ERROR_CHECK ( nrf_drv_gpiote_in_init(  primary_pin_No, 
										& int_config,
										button_drv_handler) 
	); 	
	
	nrf_drv_gpiote_in_config_t sint_config = {
		.sense 			= NRF_GPIOTE_POLARITY_HITOLO, 
		.pull			= NRF_GPIO_PIN_PULLUP, 
		.is_watcher 	= false, 
		.hi_accuracy	= false, 
	};
	APP_ERROR_CHECK ( nrf_drv_gpiote_in_init(  secondory_pin_No, 
										& sint_config,
										secondary_button_drv_handler) 
	); 
	
	nrf_drv_gpiote_in_event_enable( primary_pin_No, true ); 
	nrf_drv_gpiote_in_event_enable( secondory_pin_No, true ); 
}
  1. It works good when click each button, callbakc function is called.
  2. when i hold the secondary button(this button sense require NRF_GPIOTE_POLARITY_HITOLO or NRF_GPIOTE_POLARITY_LOTOHI) first, then click primary button, it will not enter GPIOTE_IRQHandler, two button pin in LATCH registers,are "Criteria has been met".
  3. release button from hold state, every button can generate interrupt again.

why holding a button( sense = NRF_GPIOTE_POLARITY_HITOLO or NRF_GPIOTE_POLARITY_LOTOHI), others gpiote interrupt is seem to be masked(disabled? missed?)? it that a bug of nrf_drv_gpiote ? or that is a mechanism that GPIOTE normal work?
