I have problems with custom breadcrumb when using a main-menu to set the breadcrumb as well as setting append page title.
It seems to work only after the first level see below
-item a works only displays home | title
--item b does not work displays home | title
---item c works displays home | item a | item b | title
The problem I have is I don't get any error messages so I'm finding it difficult to troubelshoot why this would be happening.
