Error: Navigator has both navigation and container props

I've started a new app that's pretty barebones. I've started it with Expo and Redux. Since the new updates to the API I've encountered this error:

I've looked at the updated documentation and cannot figure out what's going on here. Anyone else encounter this error?

Here's my code for reference:

import React from 'react';
import { addNavigationHelpers, createStackNavigator } from 'react-navigation';
import { withNetworkConnectivity } from 'react-native-offline';
import { createStore, combineReducers } from 'redux';
import { createReactNavigationReduxMiddleware, reduxifyNavigator } from 'react-navigation-redux-helpers';
import { connect } from 'react-redux';
import { colors } from './../utils/BaseStyles';
import MainPage from './../screens/MainPage';

export const AppNavigator = createStackNavigator({
    Main: { screen: MainPage },
  }, 
  {
    initialRouteName: 'Main',
    navigationOptions: ({ navigation }) => {
      return {
        headerStyle: {
          backgroundColor: colors.primary,
        },
        headerTintColor: colors.primary_white,
        headerTitleStyle: {          
          color: colors.primary_white,
          fontSize: 21
        },
        headerBackTitleStyle: {
          fontSize: 16
        },
      }
    }
  });

const middleware = createReactNavigationReduxMiddleware(
  "App",
  state => state.nav,
);

let App = reduxifyNavigator(AppNavigator, "App")

// same error occurs if I use the withNetworkConnectivity or not. If I'm not using it, I rename App on the line above to AppWIthNavigationState

const AppWithNavigationState = withNetworkConnectivity({
  withRedux: true,
  pingServerUrl: 'https://www.google.com'
})(App)

const mapStateToProps = state => ({
  nav: state.nav,
  network: state.network.isConnected,
});

export default connect(mapStateToProps)(AppWithNavigationState);
