Featured image not getting attached to post.

When I upload a featured image through the front end forms and submit, the post gets created and the image is only tied to the post by an anchor and the image in my media library is not attached to any posts. How can I get it to attach to the post in which it was created with? I just tested this on the Pro version and it seems to be attaching featured images fine.
