Blackboard parenting won't work


I am trying to get my artificial intelligence talking to each other using the blackboard and parenting. I have one character known as the “leader” which picks a spot then places it on a blackboard for the “followers” to view and then the followers go to that spot. I have my leader’s blackboard as the parent for the follower’s blackboard and am able to link to the leader’s blackboard key in the behaviour tree of the follower, however the follower’s blackboard does not update with the leaders key in game. I am getting frustrated with this as I can find very little official documentation about parenting in the blackboard and the unreal websites are a nightmare to work around.
