What kind of subtitles are invisible to MakeMKV?

I may have not noticed it before but I recently realized that not all subtitles are visible to MakeMKV.
What I am seeing are subtitles that I can select in VLC when I watch the DVD but when I try to create the MKV file that subtitle does not appear in the expanded tree and when I rip to MKV and play it back via VLC the subtitle is missing completely.

This is a real show stopper for me which means that for now I have to rip the complete DVD to make sure I am getting all the subtitles.
Any idea what may be the problem?

MakeMKV should display all subtitles. The only subtitles not processed by MakeMKV are so-called "closed captions" or "line 21" data present on some discs.

Thanks Mike for your response. Any plans on adding Line 21 (aka CC) support?

Absolutely. Can't promise any specific time frame.
