Breadcrumbs not showing proper path
An alternative is to use the Menu Position Module. 

This module allows you to create a "rule" that says all of the nodes of type "whatever" go under this menu entry.

So, for your specific case, you would go to Structure > Menu Position Rules and add a new one. Give it a name and location in the menu and specify which content type you want (or pages, or users, or terms).

This is beneficial as it means you don't need to add each node to the menu.
