Not able to get WalkingRunningDistance over a period of time

[emzudemo]

Hey guys!
First of all: Thank you for the great package.
From my understanding getting the walking+running Distance for a period of time works with getDailyDistanceWalkingRunningSamples()
But the data I get back doesn't seem to match the data within the Health app. And the dates are one month and one day off.

here's my code and what I get back.

import AppleHealthKit from 'rn-apple-healthkit';

const workoutData = [];
const startDate = new Date(2019, 10, 19).toISOString();
const endDate = new Date(2019, 10, 22).toISOString();

const permissions = {
  permissions: {
    read: ['DistanceWalkingRunning'],
    write: []
  }
};

const options = {
  startDate,
  endDate
};

AppleHealthKit.initHealthKit(permissions, (err, results) => {
  if (err) {
    console.log('error initializing Healthkit: ', err);
    return;
  }

  AppleHealthKit.getDailyDistanceWalkingRunningSamples(
    options,
    (err: Object, results: Array<Object>) => {
      console.log(results);
      console.log(startDate);
      console.log(endDate);
    }
  );
});

code gives back:

LOG  [{"endDate": "2019-11-21T00:00:00.000+0100", "startDate": "2019-11-20T23:00:00.000+0100", "value": 14484.096000000001}, {"endDate": "2019-11-20T18:00:00.000+0100", "startDate": "2019-11-20T17:00:00.000+0100", "value": 72420.48}]
 LOG  2019-11-18T23:00:00.000Z
 LOG  2019-11-21T23:00:00.000Z

Here's the data in the health app
