From the author: "The tool is using real star data and the information I could find on transforming that to the ED co-ordinate system. It's absolutely not based on the actual ED stars at all. Thus it will be missing every single procedurally generated star, and it's also at least missing all the WISE ones as well. I highlighted it here purely as a helper if people are wondering "hmmm, I wonder which ED star such and such real star is based on".
You have stumbled upon a duplicate entry. In the future duplicate detection will be added when adding an entry and existing duplicate entries will be handled more gracefully - probably with a automatic redirect and duplicates not being shown in the search list. Of course In such a way it won't break existing bookmarks, favorites etc.
In the mean time you can find the leading entry here.
