Why are my products being duplicated?

[karen1pdfk]

I have establised products in our online store that have been there for some time now. I pulled my product list up this morning and see what that these have been duplicated. We've noticed off and on for a while that some products seemed to randomly fall off of the website but we can't figure out why. Now this happens. 
All four of the lines you see here already have the same product ready to order on our website. 
What can cause this?
