The first (the centered one) breadcrumb trail on that page appears to be from a call to bcn_display(). This is likely within one of the theme files.

The second (the left floated/justified) breadcrumb trail appears to be due to a widget breadcrumb trail. As to why the widget doesn’t show up on all pages, that’s likely due to where the widget area is available (appears to not show up on some pages for some reason).

My guess at what is happening is you have a couple of different templates for your pages/categories and some have a call to bcn_display(), some have the widget area, and some have both. I suggest looking through your theme’s files and see where the calls to bcn_display() are an evaluate if the should be there or not.

Just for clarification, are you talking about unlinking a breadcrumb (or several) in the trail on specific posts/pages, or unlinking the breadcrumb that represents a specific post/page on all trails that contain said breadcrumb?

As for your second question, setting the breadcrumb trail to be unlinked is controlled at call time. This is done either via the second parameter to bcn_display(), or via the widget options when using the widget.

I’ve pushed a change to the polevaulter branch (6.4.0 development branch) for Breadcrumb NavXT that changed the way the Attachment settings are exposed (now called Media as it goes by the new internal WordPress name). Please give this a go and let me know if it allows you to do what you’re looking for, see https://github.com/mtekk/Breadcrumb-NavXT/tree/polevaulter

I am having trouble understanding exactly what you are trying to do here. From the two linked screenshots, it appears you are not using your e-commerce plugin’s archives for the category archive. Additionally, it doesn’t look like you had some of the Breadcrumb NavXT settings correct for what you want given your e-commerce plugin.

However, from what I can tell from the linked page (“The page I need help with” URL), it seems like the site works more like what you are asking for when compared to the screenshots. One thing I did notice is you have the “Hierarchy Referer Influence” setting enabled (which causes the breadcrumb trail to use the product tag if coming from the product tag archive rather than picking the first product category). Is there something else you want this to do that it currently is not doing?

The first thing I will comment on is, based on the post breadcrumb template provided, it looks like the template are using the old breadcrumbs microformat instead of schema.org’s BreadcrumbList format (which is the format I recommend).

For the example article, what is the breadcrumb trail generated by Breadcrumb NavXT? If you are getting example.come/news/ in Google’s SERPs and or Structured Data Testing Tool, I’d assume the breadcrumb trail only has “news” as a parent category for the post (but I could be wrong, hence the need for more information as to what you are seeing Breadcrumb NavXT generate).

I have not tested against Menu Plugin Mega Max, yet, so I can’t comment on compatibility with that plugin (hopefully I’ll have the time to look at this before the end of the year). As for having settings/a GUI for using an alternate title, rather than writing code that hooks into the bcn_breadcrumb_trail filter, your options are Title Trixx (uses the SEO breadcrumb title, or provides metabox for breadcrumb title if none of the supported SEO plugins are active) and Menu Magic (uses menu title and structure).

This is likely due to the plugin not being called correctly in your theme (if you enable WP_DEBUG you probably see a PHP error relating to bcn_display() not existing). Your call to bcn_display() should be surrounded with an if statement that checks that the bcn_display() function exists. For example you should be using something like:

<?php if(function_exists('bcn_display'))
    {
        bcn_display();
    }?>

for your calling code.
