Custom post types not appearing in commentluv

I’ve been using a commercial theme on my blog.
It comes with a special menu of Reviews in the WordPress dashboard. Adding any new review in the option displays the post as a review with rating and some other extra features which don’t appear in ordinary post types. It is all right.
Coming to the issue I’m facing with it,
The reviews I write appear on my blog, but while I’m making a comment using my blog link the standard post types appear in recent posts but the Reviews do not appear in the list.

What might be the reason?
Is there any solution for this ?

Thanks.
