Help!! Files showing up with ///////////////////

I am new to Plex and didn’t find an answer via Google or the forums so if this has been asked a 1000 times please forgive me.

I created a library for music. Within the library I am seeing a few things I do not understand and help would be greatly appreciated.

1st problem - Not all the music from my hard drive is showing up. What do I need to do to resolve this?

2nd issue - I see many folders that are labeled artist name then a folder below that named artist name/////////// example - Disturbed and below Disturbed//////////////// I tried matching the file but the ones I matched now are duplicated and both have parts of albums within each duplicated folder.

last issue - Not all the albums are showing up within the artist.

What am I doing wrong?

Thanks in advance!

Start by reviewing the music naming convention:
