GitBook多语言配置方法及编辑器切换语言异常问题求助

I implemented GitBook's multilingual setup following Willow's method, where each language has its own SUMMARY.md file. Here's my full configuration, along with a critical editor issue I'm stuck on:

File Structure #

Running find -L returns this directory layout:

./LANGS.md
./ch
./ch/README.md
./ch/chapter1.md
./ch/SUMMARY.md
./en
./en/README.md
./en/chapter1.md
./en/SUMMARY.md

Key File Contents #

LANGS.md #

# Languages
- English
- Chinese

Chinese (./ch/SUMMARY.md) #

# 前言
- 前言
- 第一章

English (./en/SUMMARY.md) #

# Summary
- Introduction
- First Chapter

The Problem #

The multilingual setup works correctly in the rendered/published output, but the GitBook Editor is behaving abnormally:

• It only displays the English directory structure
• I can only edit English version files
• No matter how I attempt to switch to the Chinese version, the editor stays stuck showing the English summary and chapters— I can't access or edit Chinese content at all.

I need to resolve this issue urgently.
