breadcrumb removal – help!

Hi everyone – great theme and very helpful community.

I’m trying to remove the “Home” breadcrumb text on my homepage above first post, as well as breadcrumbs on other site sections (eg, Home » EV101). I have tried to add the following code snippets below (per Mission News Code Snippets Library) – first one for removing homepage and second one for all pages. What am I doing wrong?

.home .post-header,
.home .entry-header { 
  display: none; 
}

.singular-page .post-header,
.singular-page .entry-header{ 
  display: none; 
}

The page I need help with: [log in to see the link]
