I have two problems with the Spirit theme menus

The first problem is the main menu. When I'm in the upfront editor, all of the options are in a perfect horizontal line. Once I preview the site, the contact us option is dropped to a new line. I have been working on this website for a couple of weeks and have just begun to experience this.

The second problem is that I have two main menus. I created a main menu display for the pages of the website. I wanted the title of the site, menu, and logos to appear like that on the home/splash page. However, after creating this, It created the same menu on the home/splash page at the bottom of the featured slider. So once a user scrolls down, they see another menu. If I delete the menu, it deletes the menu for the about, services, classes, etc. pages.
