My breadcrumbs are skipping a level I've got a Main Menu and am using Superfish, not sure if this makes any difference.

But in the breadcrumbs the top level of the main menu is being skipped. Eg.

Instead of

Home - A - B

My breadcrumb looks like:

Home - B

B, being the page I am currently on.

What am I doing wrong?
Drupal core breadcrumbs can be flaky at times.

Using one or more of those methods, you can control breadcrumb behaviour.
