Hey Tilak. Can you show us your code?

import React from 'react';
import PropTypes from 'prop-types';
import Guest from './Guest'

const GuestList = props =>
  <ul>
    {props.guests
        .filter(guest => !props.isFiltered || guest.isConfirmed)
        .map((guest, index) =>
      <Guest
        key = {index}
        name = {guest.name}
        isConfirmed = {guest.isConfirmed}
        isEditing = {guest.isEditing}
        handleConfirmation = {() => props.toggleConfirmationAt(index)}
        handleToggleEditing = {() => props.toggleEditiongAt(index)}
        setName = {text => props.setNameAt(text, index)}
        handleRemove = {() => props.removeGuestAt(index)} />
    )}
  </ul>;

GuestList.propTypes = {
  guests: PropTypes.array.isRequired,
  toggleConfirmationAt: PropTypes.func.isRequired,
  toggleEditiongAt: PropTypes.func.isRequired,
  setNameAt: PropTypes.func.isRequired,
  isFiltered: PropTypes.bool.isRequired,
  removeGuestAt: PropTypes.func.isRequired

};

export default GuestList;

In app.js <GuestList> removeGuestAt: {this.removeGuestAt}</GuestList>

I made a mistake before and wrote this.state.removeGuestAt instead of this.removeGuestAt. Now remove functionality is working.
