There are a couple of things you may need to change.
The first, in the Breadcrumb NavXT settings, for the “Home Template” you may need to replace %title%
and %htitle%
with “Home” (it appears it is trying to add the breadcrumb but the title is blank).
The second, for the category hierarchy, for your page, make sure only “Sub-sub category” is checked in the editor for that post. Since categories are hierarchical taxonomies, a post being a member of a child category will automatically make it an implicit member of the child category’s parent category (and the parent category’s parent, etc.). Hence, making a post be an explicit member of multiple categories within a hierarchy doesn’t really make sense as it is redundant. The behavior you are seeing is due to Breadcrumb NavXT using the first category it found with a parent category (since more than one category was returned by get_the_terms
).
