There seems to be a bug with WP’s menu and the “back to” link. When I click to view a single entry, WP’s menu gets the URL parameters appended to each item. This seems to only be affecting pages and not post categories.
That said, a person could probably hard code (ewwwwwwww) in your link in place of $href in gravity-forms-addons.php on this line:
$link = apply_filters('kws_gf_directory_backlink', '<p class="entryback"><a href="'.$href.'">'.esc_html($entryback).'</a></p>', $href, $entryback);
I’m still tinkering and if I find the issue, I’ll post the solution.
