The 88 Films release of Project A contains two Chinese audio tracks, one English audio track, and three subtitle tracks. The Chinese tracks are Cantonese and Mandarin. Presumably there are differences in dialogue between the two dubs, so they each have their own subtitle track, and the third is SDH subs for the English track.
But since MakeMKV can't tell the difference between Cantonese and Mandarin, and all three subtitle tracks are the same language...I'm not sure how to tell which tracks I'm supposed to rip or what I'm supposed to label them.
