Playlist link missing when saving to Drop Box

I am trying to save a playlist to Dropbox from my Mac, and then open it on my Ipad.

The drop box file does not include the blue link at the top that you need to click in order to open the playlist? I've tried renaming the playlist, creating a new one and dragging the songs into it, restarting the Ipad, and none have resolved the problem.

Could a corrupt song be the problem? (i've been playing with symbols in the Text fields and some songs won't open from a drop box link because of them.)

It might be the problem (odd text characters corrupting the song code). If you take them out, does it work ok?
