Double players are showing.

This is the easiest player I’ve found, and the most elegant. However, on one of my sites, two players show when I embed one link.

The first player will not play, but expands. The second player is the working player.

This is the case with a variety of browsers. There are no other audio players activated on this site.

What should I do next?
http://booksites.us/what-to-pay-attention-to-in-your-branding/ is the link where the players are showing double.
