Unknown extra link appears in my navigation links

I'm currently learning and practicing by coding my own website (so I'm a newbie), but I can't figure out why I have an extra link to the left of my first navigation links.

It only goes away if I delete my navigation links (HTML side) or if I taken away padding under the navigation in CSS, which I need to style.

This is an image of the page when rendered. The extra link is purple due to my mouse hovering: http://ift.tt/2l39UE0

This is the code: http://ift.tt/2l35P2z

Thanks for any help!
