Why do I have two menu bars in my drupal instance? I noticed while I was building my theme, that I have 2 menu bars at the top of my screen, like so:



I don't see anywhere that would indicate there would be two. 

How would I go about fixing that?
You may have 2 toolbars enabled. One is the Drupal 7 default toolbar which in my experience most disable in favor of the the admin_menu.

drush dis toolbar -y

or 

drush dis admin_menu -y 

Or under the modules config page.
