Leap Motion Gesture Detection Accuracy with LeapJS

I am using a leap motion sensor with my node app to detect gestures. With my current setup, the gesture detection is working but not as accurately as I need it to be. When I perform a swipe gesture the leap motion does not always send a swipe gesture object and when it does detect a swipe it often will send multiple gestures. For example, when swiping left, it will return a left swipe as well as an up swipe. I am wondering if this is an issue with my code or my leap motion sensor.

Here is my leap controls code:

var controller = Leap.loop({ inNode: true, enableGestures: true }, function(frame) {

  // finger location tracking
  if(frame.hands.length > 0) {
    var iBox = frame.interactionBox;
    var pointable = frame.pointables[0];

    if (pointable) {
      var leapPoint = pointable.stabilizedTipPosition;
      var normalizedPoint = iBox.normalizePoint(leapPoint, true);
      let mouseControlY = (1 - normalizedPoint[1]) * appHeight; // with leap facing up

      // invert directions for mirror
      let invertMouseControlX = (1 - normalizedPoint[0]) * appWidth;

      updateMouseCords(invertMouseControlX, mouseControlY)
    }
  }

  // finger gesture tracking
  if(frame.valid && frame.gestures.length > 0){
    frame.gestures.forEach(function(gesture){
        switch (gesture.type){
          case "screenTap":
              console.log("Click");
              break;
          case "swipe":
              handleSwipe(gesture);
              break;
        }
    });
  }
});

function handleSwipe (swipe) {
  let io = getIO();
  
  if(swipe.state === 'stop'){
      if (swipe.direction[0] > 0){
        // user swiped right
        swipeDirection = 'right'
      } else {
        // user swiped left
        swipeDirection = 'left'
      }
      
      if(swipe.direction[1] > 0) { 
        // user swiped up
        swipeDirection = 'up'
      }  

      // send swipe direction to frontend
      io.emit('swipeData', swipeDirection);
  }
}

I only need to detect a left, right, or up swipes and possibly the screen tap gesture. Is there anything I can do to optimize my code or is the issue likely my sensor?
