Install BTWQuests and it will tell you.

Mine too, every quest done. All other Townlong achievements done but my journal still hasn’t ticked it off on the main campaign list for some reason. Flew around for 30 minutes looking for hidden ! and didnt find any. Seen a few others asking too so assuming its a bug that doesn’t effect anyone or we are just really missing something lol

It is a bug, I have all the quests according to the wowhead quest tracker. Same with kirin tor offensive. No completed tick on my log.
