These books are not duplicates but two separate books.

That link doesn't work well for anyone other than you, but it shows enough of the title that I was able to take a guess at the books in question.

If you use the "Look Inside" feature on Amazon for The Laws of Thermodynamics: A Very Short Introduction, the copyright page says "First published in hardback as Four Laws That Drive the Universe 2007," so these two titles do appear to be correctly combined.
