Uncaught TypeError: Cannot read property '0' of undefined

I'm trying to use RangeCalendar inside Picker but I keep getting this error:

Uncaught TypeError: Cannot read property '0' of undefined
    at _class.getStartValue (RangeCalendar.js:671)
    at _class.render (RangeCalendar.js:169)
    at finishClassComponent (react-dom.development.js:13727)

My implementation looks like this:

import React from "react";

import * as moment from "moment";
import Picker from "rc-calendar/lib/Picker";
import RangeCalendar from "rc-calendar/lib/RangeCalendar";

interface RangePickerProps extends React.HTMLAttributes<HTMLElement> {}

const selected = [
  moment(),
  moment()
    .clone()
    .add(1, "months")
];

export const RangePicker: React.SFC<RangePickerProps> = (
  props: RangePickerProps
) => {
  const calendar = (
    <RangeCalendar
      defaultSelectedValue={selected}
      format="YYYY/MM/DD"
    />
  );

  const input = ({ value }) => <input value={value} />;

  return (
    <Picker calendar={calendar} {...props}>
      {input}
    </Picker>
  );
};

export default RangePicker;

I don't have the same issue when using the Calendar component from:

import Calendar from "rc-calendar/lib/Calendar";

Is my code missing something?
