Lightroom :: Displays Multiple Identical Images

I am in the process of organizing my Literoom images and filter displays MULTIPLE IDENTICAL IMAGES, under METADATA STATUS changed. .
 
Computer info - Literoom 4.3, windows 7, some 55,000 images on the hardrive, one catalog used.
 
When I go to folders, and click on J drive which holds these images, they all come up if filter is off of course. Now using metadata I search on a date, a camera, lense, etc. But I just want to find all of my images on a particular day. I can find those with no problem. My problem is that I may have 2 or more identical images display in grid and view as well as film strip. Looking up metadate status I find that these images are CHANGED. I understand that status, but there is no way that these multiple images would result from my work.

I searched for multiple files located in multiple folders - What is creating those multiple files, they are identical as to date, how they look, etc?

If I go to CATALOG, and work with the all the images there, found at the top of course, I get the same functionality, BUT THE MULTIPLE IMAGES ARE ABSENT.

It makes it difficult to keyword on images on a certain date, because of the multiple files.
 
Filters are NOT a powerful tool for organizing collections and keywords  when this problem exists.  My  problem is not using filters, but understanding why multiple images.
