In QuickTime Player 10.4 (855): Try to set the text track language to the language which is listed in the "Preferred languages" in the "Language & Region" in the System Preferences of your Mac. Or set to “Unknown Language”.

In iTunes (v12.5.1.21): The chapters are shown regardless of the language settings. If a file has multiple text tracks for chapters, the text track placed at the top is shown as chapters.

In Apple TV (4th generation) (tvOS 9.2-13Y234): If a file has multiple text tracks, Apple TV shows the text track in the same language of Apple TV. If not has the same one, the text track placed at the top is shown.
