Where did these folders come from

Underneath my 'Research" and ‘Trash’ Folders appear 5 folders which appear to be duplicates of some of my Folders under the Draft section. These 5 folders are not “in” either the Research or Trash folders, and I can’t remember making any folders there or how I would have gotten them there. Where might they have come from, or why do they appear there?

Presumably you dragged them there at some point. Folders are allowed in the root (at the same level as the Research, Draft and Trash folders), but they won’t appear there unless you created them.
