Hi @QU,
Good day! Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, I understand that you're experiencing an issue where you can't see all subfolders in some shared folders on OneDrive, for example, the "QU" folder and its sub-chapter folders.
I've researched and I also tested one method and found it to be quite fast and simple: creating a new folder and then moving the files. This might be a bit inconvenient, but I think maybe you should try it.
Additionally, you can find detailed information about Files and Folders in the official Microsoft documentation here: Share OneDrive files and folders - Microsoft Support
If you've tried and it still doesn't work, please create the ticket to Microsoft Support Team Contact - Microsoft Support
Hopefully, this helps clarify your situation. Please ask if you have any other questions. I'm always here and ready to help you with anything.
