I would like registered users to be able to unpublish/delete their own posts. Under Options > Permissions, I have set "Edit Own State" to "Allowed". I then can see the "Unpublish" options when logged in as that user, viewing my own post. But, when I try to Unpublish, I get an error that I do not have "Edit State" permissions. If I turn that to Allowed however, I can unpublish anyone's posts. 

Please take a look at this. If "Edit Own State" is Allowed, I should not get the error. See attached.

Also, What is the "Lock" button supposed to do? It also gives the same error message.

Thanks.
