One code embed swallowing my accordion

Hi there,

On this page:
http://www.precidia.com/emvcanada/canadian-emv-first-data/voice-auth-new/

The code embed %48% is swallowing up my accordion for some reason no matter what I do. I have this format on many other pages with no issue.

Am I missing something here?
