About two days ago my home page randomly added a second button called '#3 Untitled' to the main menu. I tried my best to go to menu's, along with settings and readings to make a new static page, but it still displays two buttons as "Home" even if I make a new one, or set another page as default. If I try to make the page 'private' then my site becomes source code or gets a 404 error when you type it in. I'm not exactly sure what or how this happened, but does anyone have any tips or ideas? I've tried everything I can think of.
When I go to 'pages' in the dashboard, I only get one 'Home' showing, the second link I can't find.
The blog I need help with is moavhist.org.
