Talk to the disc authors. It's not MakeMKV, per se, & has been discussed... a great deal.

I know it causes many others hours of re encoding to sort out as well.
Doubtful since you can always simply remux "newly discovered" subs into the mkv without any recoding. Unless of course you use hardcoded subs in your encodes which is kinda pointless these days.

This is another reason for ripping ALL audio and subtitle tracks if you're going to re-process the file anyway. You can figure out the tracks you want without having to wait for the ripping to happen again, then use that knowledge to either remux "just what you want", or to process with handbrake to compress the video and "whatever".

I've found that selecting _only_ the forced (English) subtitles in MakeMKV has been rather reliable. HandBrake has a best guess algorithm to figure out what it _thinks_ the forced subtitle is, but it's not always obvious/correct.

Most modern media players of note (Kodi, VLC, etc.) can render a subtitle track that's marked as forced on its own (mkv only, obviously) so I'm not even sure why folks burn them in any more. It's 2018...

Working with a mix consisting of 95%+ anime disks, MakeMKV's "forced" tracks have ALWAYS ended up being empty and deleted. Occasionally there will be a movie that has forced flags set.

Handbrake's algorithm is simple - count the # subtitles in each track. If you find any subtitles that have the "forced" flag, chose that track (the disk author probably understands the proper use of the flag). If none are marked as forced, whichever track has 10% or fewer subtitles than the other tracks, chose that track. It's rather effective, for as simple as it is. But it can be fooled.
