Detach not working in the media uploader on edit page

The version in use is actually 1.1.2, but that version wasn’t in the list above. It’s working fine in the actual media library, but not when you’re in the media uploader when editing a page or post.

We’d really like to be able to detach from the edit page because the media library is very large and it’s difficult to find each image to detach.

Thanks, Heather
