Thanks for both of the responses you guys. I managed to reach the builder of the website and they’ve explained what happened. I was under the impression that they were managing updates, and they thought that I was doing it. Now that the misunderstanding is out of the way, the site should be fully updated, allowing me to remove things like this in future.
I’m hoping that the updates should allow me complete access to editing, but if not I’m going to push for full privileges. This should hopefully be over for now.
Thanks again
