Dvd captions are for a different movie

On the dvd for this movie, if you turn on the captioning on your tv, it will display captions for a completely different movie!

As I was reading the first 10 minutes of the captions, I picked up on character names such as Sara, Angus, Laurel, and Thomas. The movie seemed to be discussing the death of a character named Mark. When I cross-referenced this info with other movies distributed by Kimstim, who released this dvd, I found the other movie which matched the captions -

Bridgend (2015): Sara and her dad, Dave, move to a small village which is haunted by suicides among its young inhabitants. Dave, as the town's new police officer, tries to stop the mysterious chain of suicides.
