Comments+ showing wrong article when posting to Facebook

I installed Comments+, set up the Facebook & Twitter apps, but when I wrote a comment on a post and it attributed the comment to another post and linked the same wrong post in Facebook. We have a related content plugin installed and it appears to have grabbed the first related post and used that as the post to comment on. But when I disable Comments+, comments are attributed to the correct post.

I double checked the code for the related posts plugin and it uses a WP_Query query, but then runs both wp_reset_query() and wp_reset_postdata() after. I even added storing the post to a temporary variable and restoring it after (ie, $post_temp = $post; run the new WP_Query and then $post = $temp_post:wink: but it is still grabbing the first related post, not the actual post.

Any ideas?
