Snap theme help needed

I’m hoping someone can help me. I’ve spent a lot of time trying to put my portfolio website together without much progress. I’ve never used wordpress before and I”m finding it really confusing.

When I look at the live demo, text appears when you put the cursor over the image. This isn’t happening on my site. Btw I don’t want to use any of the blog/post features – could this be the problem?

I only want the page names to appear on the menu bar at the top, but the names are also appearing below on the page with the images.

Thank you in advance to anyone who has the time to reply.
