wordpress plugin for sitemap

Might be 4.3 wordpress plugin. I activated the new plugin but the “sitemap” area at the top right corner of the http://www.jhowardco.com/website no longer shows any type of map, just this copy that has been posted by others before:

This is a XML Sitemap which is supposed to be processed by search engines which follow the XML Sitemap standard like Ask.com, Bing, Google and Yahoo.
It was generated using the Blogging-Software WordPress and the Google Sitemap Generator Plugin by Arne Brachhold.
You can find more information about XML sitemaps on sitemaps.org and Google’s list of sitemap programs.

How do I get the sitemap to display on the website now?
