extra clauses injected into some queries

This plugin may filter more queries than it should, while debugging another issue I found in a product query:
) AND wp_posts.post_type = 'product' AND (wp_posts.post_status = 'publish' OR <strong>wp_posts.post_status = 'wc-shipped'</strong> OR

In this case wc-shipped is a Custom Order Status added using this plugin, which can only apply to order and should not be added to a product query.
