[IndexTable] is not showing selectedItemsCount in Remix

[aikyahd]

Summary

None of the examples from the IndexTable is displaying selected text or number acually anything.

I'm trying this in my Remix with Polaris app.
I also checked that the allResourcesSelected is always false.
const { selectedResources, allResourcesSelected, handleSelectionChange } = useIndexResourceState(orders);

I don't think my code will make any difference, since all of the examples seems to have the same problem but here it is,

import React from 'react';
import { Card, IndexTable, Layout, useIndexResourceState } from '@shopify/polaris';

export default function ExampleListItems() {
    const orders = [
        {
            id: '1020',
            order: '#1020',
            date: 'Jul 20 at 4:34pm',
        },
        {
            id: '1021',
            order: '#1021',
            date: 'Jul 20 at 4:34pm',
        },
        {
            id: '1022',
            order: '#1022',
            date: 'Jul 20 at 4:34pm',
        },
    ];

    const resourceName = {
        singular: 'order',
        plural: 'orders',
    };

    const {
        selectedResources,
        allResourcesSelected,
        handleSelectionChange,
    } = useIndexResourceState(orders);

    const rowMarkup = orders.map(({ id, order, date }, index) => (
        <IndexTable.Row
            id={id}
            key={id}
            selected={selectedResources.includes(id)}
            position={index}
        >
            <IndexTable.Cell>{order}</IndexTable.Cell>
            <IndexTable.Cell>{date}</IndexTable.Cell>
        </IndexTable.Row>
    ));

    return (
        <Layout>
            <Layout.Section>
                <Card>
                    <IndexTable
                        resourceName={resourceName}
                        itemCount={orders.length}
                        selectedItemsCount={
                            allResourcesSelected ? 'All' : selectedResources.length
                        }
                        onSelectionChange={handleSelectionChange}
                        headings={[
                            { title: 'Order' },
                            { title: 'Date' },
                        ]}
                    >
                        {rowMarkup}
                    </IndexTable>
                </Card>
            </Layout.Section>
        </Layout>
    );
}

and since it's a local React app, here's the index.js and app.js files also,

/src/index.js

import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import { AppProvider } from '@shopify/polaris';
import '@shopify/polaris/build/esm/styles.css';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <AppProvider>
      <App />
    </AppProvider>
  </React.StrictMode>
);

and /src/App.js

import React from 'react';
import { Page, BlockStack } from '@shopify/polaris';
// import NewDiscountForm from './NewDiscountForm';
import DiscountList from './DiscountList';

export default function App() {
  return (
    <Page>
      <BlockStack gap={500}>
        <ExampleListItems />
      </BlockStack>
    </Page>
  );
}
