Users' Recycle Bins show folders in the Document Library of a SharePoint site after "Add a OneDrive shortcut"?

We created some folders in the Document Library of a SharePoint Online site. Users created OneDrive shortcuts using the "Add a OneDrive Shortcut" link on DL's web portal.

All the users then began to notice that their local Windows recycle bins showed some deleted folders deleted by other users. It even showed some of the document library's folders that are supposed to be permanently in the DL. No user has assigned permissions to delete them.

It appeared to happen to all users who have a OneDrive shortcut created to the root of the Document Library of the SharePoint site.

That made all users wonder why they saw that, and they didn't know what to do. They feared of deleting any folders and files on that document library by using the "Empty folder" option of their recycle bin.

Is that a normal phenomenon after an OneDrive shortcut has been created for any document library of any SharePoint Online sites?

Or we might have misconfigured something while creating users' permissions to the document library?

Please advise.
