OK...after further analysis, I see where my import folders are going. It's different than before where all my date ordered files were together, followed by Name files I created. Now I have most of my date ordered files as before, my named files as before and now Lightroom is putting the new date ordered files after the named files.
FWIW, I would be happy to invite one of you into my PC for a look? I can send a Teamviewer link if that's allowed? Maybe seeing it will help?
Take a screen shot and attach it go this thread at the forum website.
Figure 1 shows my SOB (K:) drive with the subdirectory Pictures with a subfolder for each year. Note that the last folder with photos is 20151025 with a subfolder jpg Export. The 20151031 you see in the screen shot was added manually by me.
If I scroll down the list, the last folder in 2015 is Winter Photos. Figure 2 Now all of a sudden, we have another SOB (K:) drive and the year folders again. Why it shows again and why the named folders shown previously are gone is beyond me.
Lightroom is not a file browser and by default does not show you the folder trees like a file browser does. To see the tree in its full branched form, you need to repeatedly:
select a folder
right-click, "show parent"
Most likely, what appear to be duplicate folders are really children of different parents.
What will this tell me?
A right click on 20151031 gives an error message "An internal error has occurred: Database "J\Users\User\Pictures\LightroomBackups\Lightroom 5 Catalog\Lightroom Catalog/lrcat" : UNIQUE constraint failed.....
