The first edition has a Polish title, description, and language set as Polish. The publisher, publication date, and translator also match the Polish edition. The only difference is the cover, which I believe to be wrongly uploaded, as it belongs to the Dutch edition, and Filia (the publisher listed in both editions) solely publishes books in Polish.
