How to apply i18n for autogenerated sidebar _category_.yml label?

[Ikalli]

I am currently internationalizing (i18n) a document written in Korean into English.

The sidebar of my document is all autogenerated sidebar.

// sidebar.js

/** @type {import('@docusaurus/plugin-content-docs').SidebarsConfig} */
const sidebars = {
  // By default, Docusaurus generates a sidebar from the docs folder structure
  exampleSidebar: [{ type: 'autogenerated', dirName: 'example-dir' }],
};

module.exports = sidebars;

I have copied the /docs subfolders originally written in Korean to /i18n/en/docusaurus-plugin-content-docs and I am translating the documents into English. However, even if I change the label attribute in /i18n/en/docusaurus-plugin-content-docs/example-dir/under-example-dir/_category_.yml to English, it continues to appear in Korean in the sidebar.

# /i18n/en/docusaurus-plugin-content-docs/example-dir/under-example-dir/_category_.yml
position: 2
label: 'Example'
collapsible: true
collapsed: false

# /docs/example-dir/under-example-dir/_category_.yml
position: 2
label: '예제'
collapsible: true
collapsed: false

I run docusaurus following step:

1. yarn dev --locale en

But in example-dir sidebar, it displays Korean, not English. Is there a way to change this to English?

This is screenshot in my real document and I'm stuck in here. There's no page for that sidebar item.
label in _category_.yml with English not working.

# /i18n/en/docusaurus-plugin-content-docs/organization-and-project/organization/_category_.yml
# Expectation: shows "Organization" as title
position: 2
label: 'Organization'
collapsible: true
collapsed: false

You have to use the JSON translation files for now
