Sorting no longer works for me

Describe the bug

Right clicking on the icon in the upper left no longer sorts. This used to work, then stopped a few versions ago. I hear a quick sound, but nothing in the bags moves (this is in the "show bags" view). Did something change, or maybe a conflict with another addon, or am I missing a setting?

Steps to reproduce

Open bag, do "show bags", right click icon to sort. Move some things in the bags off on their own, since sorting should move that back with everything else.. makes a sound, but doesn't sort for me.,
