Music not showing up in Library

I worked through your suggestions, my metadata agents were already set the same way so I went ahead and performed the Plex dance with one of my folders where some songs were showing up and others weren’t.

Unfortunately it did not work for me.

I’ve attached screenshots of what my Plex library shows, what I see if I view my music library by folder then select that particular folder, what I see if I navigate to that folder in Finder & how the tracks are tagged.
