Weird problem

I installed this and posted a player a couple weeks ago. Everything works with the first album player and it’s great!

However, I added a few more albums today and the songs are all in the post but when I pull up the pages with the new albums, the songs are not listed! The album artwork is there but no songs.

I go back and check the album “media” sections and the songs are still there!

The original post is still working great!

Any clue?
