Setting up electron Menu in OSX - Menu is blank / Menu Items not showing

I am trying to get the electron menu work. I followed this tutorial. However, although my menu shows, my menu items are mostly blank. Here is my menu file:

const Menu = require('electron').Menu
const electron = require('electron')
const app = electron.app


const template = [
  {
    label: 'Edit',
    submenu: [
      {role: 'undo'},
      {role: 'redo'},
      {type: 'separator'},
      {role: 'cut'},
      {role: 'copy'},
      {role: 'paste'},
      {role: 'pasteandmatchstyle'},
      {role: 'delete'},
      {role: 'selectall'}
    ]
  },
  {
    label: 'View',
    submenu: [
      {role: 'reload'},
      {role: 'forcereload'},
      {role: 'toggledevtools'},
      {type: 'separator'},
      {role: 'resetzoom'},
      {role: 'zoomin'},
      {role: 'zoomout'},
      {type: 'separator'},
      {role: 'togglefullscreen'}
    ]
  },
  {
    role: 'window',
    submenu: [
      {role: 'minimize'},
      {role: 'close'}
    ]
  },
  {
    role: 'help',
    submenu: [
      {
        label: 'Learn More',
        click () { require('electron').shell.openExternal('https://electron.atom.io') }
      }
    ]
  }
]

if (process.platform === 'darwin') {
  template.unshift({
    label: app.getName(),
    submenu: [
      {role: 'about'},
      {type: 'separator'},
      {role: 'services', submenu: []},
      {type: 'separator'},
      {role: 'hide'},
      {role: 'hideothers'},
      {role: 'unhide'},
      {type: 'separator'},
      {role: 'quit'}
    ]
  })

  // Edit menu
  template[1].submenu.push(
    {type: 'separator'},
    {
      label: 'Speech',
      submenu: [
        {role: 'startspeaking'},
        {role: 'stopspeaking'}
      ]
    }
  )

  // Window menu
  template[3].submenu = [
    {role: 'close'},
    {role: 'minimize'},
    {role: 'zoom'},
    {type: 'separator'},
    {role: 'front'}
  ]
}

const menu = Menu.buildFromTemplate(template)
Menu.setApplicationMenu(menu) 

I am not getting any errors, but the Menu items are just simply blank. I am on OSX, El Capitan.

In my main process I require the menu like so:

function createWindow () {
  //...code for main menu
  require('./menu/mainmenu')
}

I have also noticed that using

const {app, BrowserWindow, Menu, MenuItem} = require('electron')

did not work, (gave me a syntax error), so I did

const Menu = require('electron').Menu

instead. I am not sure if this makes a different or explains anything.
