Some files/folders show the “Put Back”, some others only shows “Delete Immedialtely…” what I found is all of those files are stored in this folder:
/System/Volumes/Data/Users/the_carthaginian/Google Drive
So the app called “Backup and sync from Google” is responsible of this strange behavior, some people are talking about it here
The folder belongs to another user, so it appears to be a shared folder in my Google Drive and was not owned by me.
