I'm using GPS Tools to include a track of a walk for a Walks festival with RSEvents. I tested this out in March and it all worked correctly, but the customer decided to delay the project for a few months. Now when I include a GPS track within the RSEvent description, it only displays the code {GPSCONTENT ["id": 2, "elevation": 1, "speed": 1, "hr": 1, "description": 1]} on the front end. 

I've also tested it with a K2 item, where it works correctly and also in a simple article, where it displays the header but not the track. 

I've attached screenprints of the 3 examples, the site is a test site behind a protected directory.

Any suggestions?
