I sold out of my item in a day and didn't have stock control on the listing so it ended. I quickly created a new listing but a video review points to the old listing. I relisted the old listing and now the link works and redirects them to the new listing, but I am left with two active listings. Which one can I end?

If you are talking about the compressors - there is only one there - not 2. And you are away till 17th.
