As seen in the picture using KMPlayer I can see that this particular movie has forced subtitles (auto) but when I put the actual file into MKVToolNix I do not see the subtitle to turn it on, It’s nonexistent. Am I missing something this has happened to me in two movies so far. The file is there somewhere because when I turn it on in kmplayer they play fine!
It might be a CC subtitle track. I’ve had that issue before, and had to use a different application to extract the subtitles.
You can install MediaInfo and see if it provides more detail.

It’s likely that this isn’t actually a real track, but a virtual one added by your player in which it filters out all subtitle entries that aren’t marked as “forced”. The thing with forced subtitles is that there’s no track header field for them in MPEG transport streams. Instead, each subtitle track can contain forced & non-forced entries, in arbitrary order — and there’s no way if there actually are forced entries without reading the whole file & checking all the entries.
