Sidebar Login Not showing on Home Page

The website I took over to manage is using a sidebar login for the faculty. It appears on every page except the home page in the upper right hand corner. Actually, I can see the login button appear for maybe a second on the home page before disappearing. It lies on the same line that a Facebook redirect is at, and the Facebook button is fine on every page. From the properties of the sidebar, I don’t see anything special restricting it from the home page. New to websites and wordpress, so hopefully I didn’t miss something obvious.
