I uploaded the book https://commons.wikimedia.org/w/index.php?title=File:Zawis_and_Kunigunde_(1895).djvu&page=1 using IA uploader. The IA uploader showed me the page with the title Zawis and Kunigunde as the first page of the book and asked whether I want to remove it. I ticked "No", as it was a part of the book. However, after the upload was finished, a completely different page appeared there at the position of the first page. The one I was asked about appeared on the position of the 2nd page after the upload. As the uploaded first page is completely useless, I would have asked it to be removed, if I were asked about it.
To see which page IA uploader originally showed as the 1st page of the book have a look at the screenshot https://drive.google.com/file/d/16j-KROmg7tpHxqqp1koEV1vnHsBSctAf/view?usp=sharing
