paulg70204950 wrote My Elements 13 organizer won't open anymore so I can't show a direct compare. Basically I only had 'year' folders at the root along with a small handful of misc folders. All the folders shown below 2017 should be inside the year folders.

Set your left folders panel to 'tree view', not the flat list view.
Use the menu just right of the 'My folders' title.

You are showing the 'list' view which shows only the subfolders in the lowest tree hierarchy, omitting their parent folders. The files are sorted in alphanumeric order. That may be helpful for some types of searches, but the tree view is more usual. It works about the same as in the Explorer or Finder but it does not show empty folders by default. If you want to see all subfolders including those without images, right click on the parent subfolder and choose to show all files.
