Unable to move nodes in Non Base Layer version 2019.03.0b7

Is there a existing max to Nodes under a layer with blend trees?
I have a fairly complicated one. But I cant move the nodes around to be organized.
I wanted to add more weapons but unless I can make more nodes that I can move around I can't do that.


And here is where the issue lay. See it covering other nodes? I can't move them out from under it. They are still selectable...but not movable.
Is there something I'm misunderstanding?
The base layer works perfectly fine, and they can be moved around all over the place just fine.
