If your breadcrumb with Crumbs is not what you expect, there is a thing you can always do before you post an issue:
Copy / remember the path of the page where the breadcrumb does not work as you wish.
Admin > Structure > Crumbs > Debug
Type / paste the path into the text field, and hit Enter.
Now you get an overview of the plugins involved in determining the title, the parent, and the title of the parent, for the path you just entered.
