That is indeed the fact with blackboard variables. The reason why this is happening, is because blackboards are serialized as a whole (object) in json containing the variables, rather than separately/normal via the Unity standard serialization system. That is because blackboard variables support more type than what Unity typically does.
To get around this, I will have to change the serialization of variables completely, which though it is something that if I do, will break backwards compatibility. With that said though, I do plan to address this in one way or another in the future.
