Description
Summary of the bug:
ffprobe does not display/support multi language chapter titles. If a chapter title is available in multiple languages, only the last title in the language list is displayed.
Moreover, titles are always displayed regardless of the language without any specification.
Here is a manually edited MKV file with MKVToolNix featuring to sample chapters. The first chapter have 2 titles in FR and EN (FR being the first) and the second chapter have a simple title with "undefined" language.

Please provide your sample, please test current FFmpeg git head and please only report issues against ffprobe that are not reproducible with ffmpeg.

Sorry for the reply delay.
As suggested, I've tested with FFMPEG GIT (Wed, 11 Apr 2018 03:15:54 +0000 (11:15 +0800)) and, as expected, I got exactly the same result :

I attached a MKV sample (generated as the real content is irrelevant) featuring 2 chapters. The first one is multi lang, FR and EN and the second chapter is "undefined" language.
The chapters were edited with MKVToolNix GUI - https://mkvtoolnix.download/ -

Hi,
I thought to do so at first but ffprobe is the tool I was using when I found the issue. Besides, ffmpeg info is quite scarce compared to ffprobe and produces an error message (expected of course since we don't provide enough arguments). That's the reason why I was reporting against ffprobe even though I'm convinced the issue lies in the MKV parser of ffmpeg lib.
