Can't edit my Pitch post due to "new user" error

Still having issues trying to edit my pitch post (Replace the reference types weak and unowned with nonstrong). In your previous reply you indicated you bumped my trust level. However now when I click on the edit pencil, it takes me to a page labeled "History". On this page is the proposal, but the text is not editable and there's no "Edit" button.

I'm logged in (as myself, the origin author of the post). I looked around in the hamburger menu and various other places to enable edit, but am unable to figure it out (possibly I still don't have edit access).
