What are "Duplicate Lots" in store inventory?

Emporiosa

I noticed I had 3 "duplicate lots" showing, and when I went to inspect it, I didn't see any duplication on this site or the other for those 3 parts, so I was wondering what these are?

I don't know about duplicate lots but is it showing in the Tasks section of your Dashboard? If it is you can usually click on those messages to see what it's referring to.
