XF 1.5 Registered users can't edit their posts

I did some housekeeping yesterday, setting registered users as the default and then having other groups inherit those positions, with modification for each group. The problem is that when I finished, my registered users lost their ability to edit their own posts, even though I enabled this in Admin CP. I took a single user who is only in the registered user group and did a permissions analyze. This is what I got:


He still doesn't see the edit button. Ideas?
