I'm using an x-theme template for my site am having an issue with the page design as it defaults to a formatted field (with a weightlifting graphic and discount) that I don't have access to editing whenever I post events (http://www.axiscw.com/event/kristi-yoga/). I'm not sure where to edit this field, so I tried deleting all of the image assets in the media library that were related to this theme and even though all my media assets have been deleted (apart from what is needed for my site) this image remains. Ultimately, I would like to be able to edit this field, but don't know where to access this on Cornerstone or otherwise. At the very least, removing this image (which is nowhere to be seen in Media Library) would be helpful (image: http://www.axiscw.com/wp-content/uploads/2018/04/asd.png).
Thanks in advance for any help you can provide!
