Editing the Magazine Basic theme

I just installed the “Magazine Basic” theme and would like to get rid of the “music” category listed below the header. It’s the only category I have and when I go to the “categories” area in the dashboard, there isn’t an option to delete it, as it’s the only category.
In fact, there’s text that says, “Deleting a category does not delete the posts in that category. Instead, posts that were only assigned to the deleted category are set to the category Music.”
It’s a visual thing. I want to eliminate it. Suggestions?
