00800.mpls is the file you want.
It has onscreen subtitles for the alien language. Other file it is left out and will not know what the alien predator is saying.

So I figured it out. I was watching side by side. 00800.mpls is the file you want. The difference is it has the subtitles for the predator alien translation on screen. The other file is blank and you will not know what the predators are saying.

Did you ever figure this out? I just took both files. Not sure what the difference is yet.
