RTC1 timer reset after sleep

I configured my system to sleep after inactivity time.

  nrf_gpio_cfg_sense_input(WAKE_UP, NRF_GPIO_PIN_NOPULL, NRF_GPIO_PIN_SENSE_HIGH);
    err_code = sd_power_system_off();

when the system wake up from sleep (I use external acceleromter to wake up the system), the RTC1 timer value reset !!!

I use the following method the read RTC1 timer

uint32_t ticks_per_second;
    app_timer_cnt_get(&ticks_per_second);

how can I prevent the RTC1 timer from reset at sleep
