We have not experienced this kind of problem yet.
The plugin is tested on WP 4.7
I have also tested the plugin with LAYERS theme, it works properly. Please find the attached screenshot. The section that contains the bread-crumbs is appeared, that is missing on your site.
Maybe you have applied a design setting that is conflict with our plugin.
Please try to switch off displaying related items on bottom of your page or in widget section to find out whether the problem disappeared.
We can test this problem if we can simply set the same bread-crumbs section in our own test site. If it is possible, please let us know how can we set the area that is missing on your page.
