Adding Songs via FTP site to My Songbook IPhone App - Help

When I open the file in My Songbook I Phone app the Save button is greyed out and therefore cannot save the song. Is there something I need to have in the song for the button to be enabled?

I do have [Song] at the beginning and [/Song] at the end on one song and not on another and they both operate the same.

Any Help would be appreciated.
