HELP!!! text is duplicating all over screen

I installed the Highend theme on my website (miamimxparksupport.com) and text from the menu is running all the way down my screen. I went into the cpanel and deleted the theme and tried a fresh install. But it just makes it worse every time I reinstall it. It keeps adding pages upon pages. I can’t figure out what I am not fully uninstalling. Please help I am desperate and a very frustrated customer.
