User error. I found my own mistake after looking more carefully at my folders and Finder.. thx for the response anyway.
But while I have your attention. I am curious does LR store or make files in Finder that display Collections?
No Collection are part of LR only.
A collection in LR is just a Grouping of images. No images are moved or copied.
Like making a list of the objects in your home. You can make 20 lists of those objects and you still only have one of each.
