How is the site calling the breadcrumb trail? The site in question seems to be using a wrapping div element that is missing the schema vocab and typeof attributes (it looks like it is using an old recommendation for the Breadcrumb NavXT calling code). The recommended calling code is:
<div class="breadcrumbs" typeof="BreadcrumbList" vocab="https://schema.org/">
<?php
if(function_exists('bcn_display'))
{
bcn_display();
}?>
</div>
That will get the schema.org markup to be recognized. If you are using the widget, you probably should select the “Output Trail as” value of “Schema.org BreadcrumbList (RDFa)”.
installed and activated the plugin. When I add the code it outputs 2 lines of breadcrumbs, how can I disable the standard output?

how to disable standard output?
Breadcrumb NavXT doesn’t by default output the breadcrumb trail twice, my guess is the original call to bcn_display() was still there somewhere. It looks like on the page you linked to earlier that there is just one breadcrumb trail, and that the validator seems to find the BreadcrumbList element, are you still having this issue?
