and you read this again,

Problem: Sometimes are the covers in the book in Kindle Paperwhite moved downwards.

It appears usually with Covers with "Moiré-effect". I convert my books in Calibre from epub to mobi. After converting the result in Calibre is fine. The overview in my Kindle Paperwhite is also fine. But when I open the book in Kindle Paperwhite I see 2 covers downwards.

In my Attachments you can see
1. Not working Cover with Moiré-effect
2. The faulty view in my Kindle Paperwhite
3. A edited Cover with working view in my Paperwhite
4. The conversion log from the wrong file
5. The conversion log from the working file
6. Source.epub

Hope you can help me wich setting in Calibre I have to change or what the reason for this fault is.
