Can't move folders to the trash
Since upgrading to Catalina, 30 folders appeared in the Macintosh HD finder window. They were not there before. See below. They are dated between 2017 and 2018. I cannot drag them to the trash and when I right click, "Move to Trash" is not there as an option. There doesn't seem to be anything in these folders.
I have restarted, tried holding down command, option, control, fn, while trying to drag the items to the trash.to no avail.
