Well you can stop panicking as that is only seen by the Administrator...which in your case must be YOU!
The theme you are using looks to be the Essential theme, and that section of the page which is in the Footer, is a hidden area for the Administrator to add blocks that they wish to be kept out of view of the site users.
I hope this explanation helps?
If not then please let me know.
