Hi
For menu icon in center you need to make so many changes in plugin css file and the css file path would be: http://thevibetribe.co.nz/wp-content/plugins/menu-image/menu-image.css
Also for manu below the header you have to make css and html changes for html changes you need to access header.php file where you can see the logo div and the menu div and for css you need to access style.css file where you can find the css of .logo and .nav
We have send screenshot to your registered email address for hide loading icon and section title image.
Thank You
