That's really weird. At first I thought maybe it's a problem with that specific forum not allowing you to do it, so I created a test thread in there and tried it


I can edit the thread title from both the "threads started by" search page as well as directly in the sub-forum itself. I tried it alongside a thread in a different sub-forum too, just to be sure.

(ps, you can go ahead and delete my thread in the Resto area, I'm not planing on doing a resto anytime soon!)
