It appears possible that post notices can show up twice if moderators add them to the post at roughly the same time (in this case, it was only about 3 seconds apart from the edit history):

If I revisit the mod menu, I can remove the post notice and it removes both, then I can re-add it as needed. Not sure if it needs to be addressed as it's probably infrequent enough, but it might be a sign there are other race conditions possible for simultaneous edits to posts.
