This is very likely something your theme is doing then. Either it is calling bcn_display() multiple times on a page, or it is applying the tha_breadcrumb_navigation filter more than once (or doing both, which it should not be doing). Your best bet is to find where the theme is calling Breadcrumb NavXT and make your own version of that file in your child theme, ensuring only Breadcrumb NavXT is called once and where you want it to show up.

As covered in the Breadcrumb NavXT documentation, the first parameter for bcn_display() will have it return a string rather than echo the content. Thus, you probably want to use bcn_display(true) instead of bcn_display().

Breadcrumb NavXT uses the “Posts page” from Settings > Reading for the Blog breadcrumb URL. The easiest way to make this link to where you want is to update this setting in WordPress to link to the /blog page rather than /blog-old. If for some reason this is not feasible, you can write a filter for the bcn_breadcrumb_url hook and set the URL to what you want it to be.

Internally, there is only one title in Breadcrumb NavXT for each breadcrumb. If you just want to shorten the title shown in the breadcrumb trail so things fit nicely in your layout, consider using CSS to shorten the title (see https://mtekk.us/archives/guides/trimming-breadcrumb-title-lengths-with-css/).

Otherwise, there is another way of doing this that may help you do what you want. You could use bcn_template_tags to create your own template tag (either for the shortened or the un-shortened title). Then update your templates to use the new custom template tag.

Checking against the $id ensures you replace the title only for the page in question.

There isn’t a $htitle parameter for the bcn_breadcrumb_title filter, so that won’t work. Changes made to the title using bcn_breadcrumb_title will affect both %title% and %htitle%, there isn’t really a way around this. %title% is literally %htitle% run through esc_attr() and strip_tags().

For creating a special new title for hovers, I’d suggest creating your own custom breadcrumb template tag using the bcn_breadcrumb_tags filter. The documentation has a link to a simple example, you can use that as a starting point.

Since pages can be the root for other post types (e.g. ‘page for posts’ in WordPress core, and root pages in Breadcrumb NavXT), the page post type is treated in a special manner in Breadcrumb NavXT. Breadcrumb NavXT, at least what is exposed by the settings page, only allows pages to follow a post parent hierarchy. If you want to have a hierarchical post type follow a taxonomy term based hierarchy, you probably want to create a Custom Post Type to do that.

Well, that’s odd. Based on the output, there are really only two things I can think of that would cause this. Either the unlinked template is missing the %htitle% tag, or the instance of the post that Breadcrumb NavXT gets is missing its title (e.g. tribe is doing something weird).

To check for the first possibility, in the Breadcrumb NavXT settings page, can you look under the Post Types tab for the “Event Template (unlinked)” setting and see if it is different from the other custom post type unlinked templates?

Unfortunately, the actual code you’d use is highly specific to the intended use case and UI you are integrating into. In general, you’d do something like the following:

add_filter('bcn_pick_post_term', 'my_bcn_pick_term_filter', 10, 4);
function my_bcn_pick_term_filter($term, $id, $type, $taxonomy)
{
if($id === POST_IN_QUESTION)
{
//GET POST TERMS HERE
//Set $term to desired term for post
}
return $term;
}

Note that there are items here that you will need to write (e.g. retrieving the terms for the post, dealing with the post in question check). This may even not be the way you want to do it (depending on how you’re dealing with the mapping).
