Old page showing up

Hello,

I’m new to wordpress and decently new to web development. I’m working on a site for a client, replacing their old wordpress site with a new one.

The site is http://www.cminsulation.com

I have a home page set with my current theme, however, when you click on the Home on the top menu, the home page from the old site shows up. I cannot find the files for this anywhere, including filezilla when I log in.

The page is not listed inside the wordpress dashboard either. I want to delete this page permanently so it stops over-taking my actual home page.

Thanks in advance for the help!
