Bug in level blueprint?

Hi, I found that in Level Blueprint when I want to use the blueprint only object variable as the Object Value in some blueprint functions e.g. Set Value as Object (to blackboard), then these functions get null (debugged in vs) instead of the object connected. If I place the object to the level(map) and make blueprint reference to it and use it instead of the blueprint only variable then everything works fine. ( I tried that with my custom c++ objects derived from UObject or AActor, marked as BlueprintType ) It seems like a bug, is it ?
