Audio Player Issues

Hi,
I’m having issues with audioplayers showing up my main page. I tried the wp-audio player and entered the code in the[audio:fullfilename] format into the html version of the post. The page shows [audio:fullfilename] on the page though. When I click the post, the audio player does pop up. I also tried the SSG Google Audio Player and had the same issue of the code showing up on the main page and the player showing up on the post page. My website is https://www.themisseducation.com. Does anyone have any ideas what the issue could be. Thanks!
