TowelMan, we just switched over to the new battle.net parser so updates will happen in real time to what you see on battle.net. If you give it a try now it should work.
Still having trouble. Just tried now [look at wowarmoury it does show that the item is unequiped] and still get the same error (i.e. [#AJ-9001] According to WoWArmory.com, you still have the specified item equipped. Wait a bit longer and try again.)
