With Catalina 10.15.1, Books (Swedish Böcker) 2.1 (1849) there is no cmd-I available, which makes these errors uncorrectable:
• Importing an audio book from a group of CDs gives me one book per track. I listened to a Hemingway and had every sixth minute to open next chapter separately. In this case the track names on each CD differed from the other CDs, which at least made it possible to follow the book.
• In another audio book every CD had the same track names as had all the other CDs, which resulted in separate books for every track as before but with all track 1s from all CDs in a row. Impossible to get it in chronological order.
• Importing an mp3 DVD with all tracks on the same disc and all indexed in chronological order worked once. Other times all tracks were mixed (couldn't be read in chronological order). In one case all track names became changed to the book title without index. I erased the audio book from both the computer and my iPhone and imported again, but the same thing happened again.

track name om DVD: "0014_Kvinnan_i_fönstret.mp3"
track name in Books: "Kvinnan i fonstret" (observe the peculiar changes)
After another erasing, I removed the first zero from all 112 tracks. After import they were all again called "Kvinnan i fonstret". In my iPhone the audio book opens with chapter 70…
