Thanks for your help. There are a few of us who have worked on this so it is possible some changes were made.
For now I’ve figured out a workaround to get results I’m ok with. Instead of creating a custom menu I’ve left the menu dropdown on the default option so it just displays all the top level pages. It adds a “home” link, which is fine.
Because I didn’t want the drop down menus to display sub-pages on the site, I added the bold below in the css:
#access ul ul a {
display: none;
…
}
