I just demuxed Eight Below, purely to see the subtitle information and if the english SUPs contained any forced captions and there's a discrepency between the subtitle track numbers displayed at the beginning of the log and those used at the end to display forced caption info. Here's the log so you can see what I mean:

Done.

As you can see, at the beginning of the log, the subs are listed as using tracks 13-28 and indeed, these are the numbers used in the filenames of the demuxed subs but right at the end of the log, subtitle tracks suddenly go from 14-29, is this a bug?
