To give you an idea of the problem I have, when we use our basic template, a black box (Our original header before my time) appears, though it does not appear on the published page. This only happens when using the template, not a blank page. Is there a way to edit the template or copy the template and make a new version without it? It's really hard to edit text this way. I'm only an intern, and they've worked with it like this for years.

Here is a screenshot. Any advice would be appreciated.
