Hmm, it seems you uploaded your chapters as single texts, so it makes sense that they would be ordered lexicographically (which means 10 is smaller than 2, when considering each character after the other). You could work around that by changing the titles of the chapters to “Kapitel 01”, “Kapitel 02”, …
Thanks for reporting. I’ve created a fix by using a natural sort ordering. It won’t be deployed until early next week though.
Thank you. I will be doing 01 numbering then.
