I am on Mac, so this could account for differences in what HookerHeels and I are experiencing (I have more than just the miscellaneous tab). I've actually noticed that if I selected the scenery group to with a specific element pertains, then it falls under that group versus miscellaneous; however this only complicates things because certain element types (ie: benches) are no longer all together. Also of note, unlike HookerHeels, my save format has not changed (not sure if that is GitHub specific).
