Apple Books: footnote has a line break, after which nothing is shown.

Hey everyone,

Currently, I’m reading a book which contains a few footnotes with useful information. One footnote apparently has a line break. The paragraph after this line break is not included in the footnote view. Also I cannot view the footnote at the end of. The book, there the editors only provided the sources.

For understanding what I mean, please view the attached picture.

thanks for your help!
