Issue: Wiki not showing were it should be

I first added the wiki as a sub-forum to my hidden moderators forum, following the instructions.
That turned out to not work well. The wiki link was showing twice in the hidden moderators forum and was also showing for regular users.

I then changed the location of the wiki forum link to not have any parent forums.

But it now still shows up as a moderator sub-forum (and there are still two links).
