File selection changes MUI styles of unrelated components

Bug Report

Describe the bug

When I submit a file for upload, it changes the MUI components of unrelated components (see screenshot of Header before and after)

Steps to reproduce

Code:

import * as React from 'react';

import Header from "CommonElements/Navigation/Creative/Header";
import Dropzone from "CommonElements/Navigation/Creative/Upload-Dropzone";
import { DropzoneArea } from 'material-ui-dropzone';

function About() {
  return (
    <div className="home">
      <Header />
      <DropzoneArea
  onChange={(files) => console.log('Files:', files)}
/>
    </div>
  );
}

export default About;
