System.sleep issues using CHANGE

Hello, I have an Argon connected to 2 float sensors and would like the device to sleep until awake by digital pin change. Issue I am having here is that device keeps on awaking right away after sleeping eventhough no pin change. Here is my code.

#include "Particle.h"
#define FLOAT_SENSOR0  D3     // the number of the pushbutton pin
#define FLOAT_SENSOR1  D6     // the number of the pushbutton pin
int currState[2] = {0,0};
int float_value = 0;

void setup() 
{
  pinMode(FLOAT_SENSOR0, INPUT_PULLUP); // initiate the sensor
  pinMode(FLOAT_SENSOR1, INPUT_PULLUP);
  Particle.variable("float_value", float_value);
}

void getsensors()
{
  currState[0] = digitalRead(FLOAT_SENSOR0);
  currState[1] = digitalRead(FLOAT_SENSOR1);  
  switch(currState[0])
  {
    case(0):
      if((currState[1] == 0)){
        float_value = 0;
        Particle.publish("Level is above 70%", PRIVATE);
        break;
        }
      else if((currState[1] == 1)){
        float_value = 1;
        Particle.publish("Error Float", PRIVATE);
        break;
        }
    case(1):
      if((currState[1] == 1)){
        float_value = 2;
        Particle.publish("Level is below 20%", PRIVATE);
        break;
        }
      else if((currState[1] == 0)){
        float_value = 3;
        Particle.publish("Level is around 40%", PRIVATE);
        break;
        }
  }
}

void loop()
{
    getsensors();
    delay(5000);
    pin_t wakeUpPins[2] = {D3, D6};
    InterruptMode edgeTriggerModes[2] = {CHANGE, CHANGE};
    System.sleep(wakeUpPins, 2, edgeTriggerModes, 2);
}
