How to add new servis to ble_app_uart example ?

Question

Hello everyone, 
 I am trying to add new service into ble_app_uart example. I compile successfully. I do not get an error. But the device is not advertising. I can only advertise when I run the ble_app_uart example or when I just run my own example.But when I want to run two instances of services in one instance, the device does not advertise. My code as shown in below; 
 Function for advertising; 
 static void advertising_init(void)
{
 uint32_t err_code;
 ble_advertising_init_t init;

 memset(&init, 0, sizeof(init));

 init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
 init.advdata.include_appearance = false;
 init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

 init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
 init.srdata.uuids_complete.p_uuids = m_adv_uuids;

 init.config.ble_adv_fast_enabled = true;
 init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
 init.config.ble_adv_fast_timeout = APP_ADV_TIMEOUT_IN_SECONDS;

 init.evt_handler = on_adv_evt;

 err_code = ble_advertising_init(&m_advertising, &init);
 APP_ERROR_CHECK(err_code);

 ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
} 
 Function for initializing service; 
 static void services_init(void)
{
 uint32_t err_code;
 ble_nus_init_t nus_init;

 memset(&nus_init, 0, sizeof(nus_init));

 nus_init.data_handler = nus_data_handler;

 err_code = ble_nus_init(&m_nus, &nus_init);
 APP_ERROR_CHECK(err_code);
	
 /*********************************************/
 ble_kls_init_t kls_init;

 // Initialize KALE Service init structure to zero.
 memset(&kls_init, 0, sizeof(kls_init));
 kls_init.evt_handler = on_kls_evt;
 
 BLE_GAP_CONN_SEC_MODE_SET_OPEN(&kls_init.open_door_value_char_attr_md.cccd_write_perm);
 BLE_GAP_CONN_SEC_MODE_SET_OPEN(&kls_init.open_door_value_char_attr_md.read_perm);
 BLE_GAP_CONN_SEC_MODE_SET_OPEN(&kls_init.open_door_value_char_attr_md.write_perm);
 
 err_code = ble_kls_init(&m_kls, &kls_init);
 APP_ERROR_CHECK(err_code);	
	
} 
 
 UUID; 
 static ble_uuid_t m_adv_uuids[] = /**< Universally unique service identifiers. */
{
 {KLS_UUID_SERVICE, BLE_UUID_TYPE_VENDOR_BEGIN }
}; 
 
 Added new service instance;
