9781742379 is not a valid ISBN10; it's what happens when someone entered the ISBN13 in the ISBN10 slot -- it gets truncated.
Since it was shelved by more than 5 people, you'll need to separate out those two editions (so they are only combined with each other -- the separate tool is good for this) and post a merge request in this thread: https://www.goodreads.com/topic/show/...
Edit: Ah, sorry, you're not a librarian. Ok, just post links to both editions in that thread.
