This likely is happening through the DictMapper, when you call set_id on it and it resizes it's internal Vec with a bunch of "".

Research direction
Start with the linked Slack threads and trace the DictMapper path involved when set_id resizes its internal Vec. Investigate how send_graph behaves for a subgraph and confirm which operation creates the fake layer. Done means calling send_graph on a subgraph no longer produces that fake layer.
