Something funky with the homepage presentation on the page menu bar

Could you please check the homepage and menu bar at www.mygirlsgroup.com and let me know what I have done? I never named a page HOME, yet it is there. I did use the page since it was there. However, when I change sidebars for example on all pages, this mystery page is not effected. I also can't figure out for the life of me what those little boxes are to the right of the HOME tab but they are certainly associated with the page. When I look at the list of pages in the dashboard it is nameless, another mystery, it doesn't say Home.

Thank you in advance for clearing this up for me!
