do not worry about the output being disabled in a RedisSet output node. That "output" refers to the engine connection.

An output node is "final": it receives messages from the engine but do not send messages back to it.
Regarding the NGFW not receiving the EDL: have you tryed to grab the EDL with a browser to identify if the issue is at the MineMeld side of the connection?
