A Microsoft file hosting and synchronization service.
Dear Nader Ghodoosian,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
From your description It seems OneDrive showing shared folders behavior from your side.
If my understanding is right, apologized situation you encountered, we do understand the inconvenience caused and apologize for it. And I just tested from my side, and it seems its expected behavior. The shared section is for keeping a note of what files have been shared with you in earlier in order to access them fast and easy. This is the expected behavior. if you dislike seeing the shared folders you can give feedback to our feedback website OneDrive · Community (microsoft.com)
Your understanding and patience will be highly appreciated.
If there is any misunderstanding, please feel free to correct me.
Have a nice day!
Best regards,
