The first link was a duplicate (with a truncated isbn) of an edition that was correctly combined with the Omnibus editions. Separated both, merged into the valid edition and recombined.
As for Silo - épisode 1: This is definitely only Episode 1 (= part 1 of 5), but the Amazon page count indicates the complete book (which I've seen before on Amazon on preview editions that are listed with the page count of the whole book). Unfortunately, for Kindle editions we have to use the Amazon page count, so we can't remove or change the page count.
