[Theme: Real Property] – Remove menu from header

I purchased this theme and imported their dummy data. My site is located at SouthernModernHomes.com. As you can see, there is a pesty menu at the top left of the site. When I contacted theme support they told me to go to Appearance/Menu to correct it. I deleted the menus that were included in the dummy data but alas, the menu is still there. Any suggestions would be appreciated since the support crew behind the theme do not seem to want to give direction beyond going to the Menu page. Thank you in advance for guidance.
