Folders left behind with .jpg file after moving files despite *.jpg in clutter

Problem

Folders that are processed by beets (all music files are moved out of the folder) are not always being deleted. Often times they are left behind with only a single .jpg file remaining even though I have *.jpg added to my clutter list.
Setup
