Header Image Squished/Menu links missing

I’m a beginner to WordPress, so I really didn’t know how I changed things around. I tried to edit the menu on my page and it turned it into a pulldown menu that sits at the very top of the page. Also, the header image is now “squished” at the top of the page. I would like the regular menu hyperlinks I had previously with this theme and as well as fix the header image. Any ideas?
