Subscriber Actions from one list to another


So all of my lists are set to "When a subscriber will unsubscribe from this list, if he exists in any of the lists below, unsubscribe him from them too." So when I merge a few lists together and it creates a merged list of all the other lists it looks like that option is enabled also. But if a subscriber unsubscribes from the merged lists it doesnt unsubscribe them from the previous list. It still shows as confirmed.
