I used '-map_metadata 1'.
I can try -map_chapters, but if I would be using the wrong option, I
would expect everything to go wrong and not only the first chapter.

I tried it, but it is just the same problem.
It looks like ffmpeg wants the first chapter to start at 0 and that
chapters need to be connected. (Chapter n ends where n + 1 starts. But
why do I have to enter the end of a chapter then?)
