Problem with a theme

I recently started to work on a website and decided to use a template. I wanted to use a static page instead of the posts for my front page. The problem I found early on is that WP automatically creates a home page and since I know very little php, I needed a workaround. Well, I found a way to bypass having to edit the index.php file by using the pagesmash plugin to hide the about us page but pointing the start page to the contents of it.
It seems to work fine except that there is a small double-arrow graphic on the last of my menu items as if to signify there are subpages but there aren’t.
Can someone take a look and give me a hand. The address is: https://www.ethertrends.com. Thank you.
