Among the many skills we possess, we manage a number of content management systems (CMS).  Our preferred CMS is Joomla and it seems there's always something I end up hunting down.  On a recent project, "Home" appeared on the frontpage of a client's site.  Initially, I thought it was a breadcrumb but after a little digging around, I discovered the source:

From the top of the Joomla Administration screen, select:

Main Menu

On the right side of the screen, select:

Page Display Options

Set "Show Page Heading" to "No".
