Hey Joël B., just a simple check 😄 ... on the Gate Snap, the "Ignore Empty Stream" checkbox is checked or unchecked?
If it is unchecked, the Snap writes an empty document to the output view even there is no input data going to the snap.
Hey Brian C., if you have the disabled snaps connected with the upstream snap, the output of the upstream snap will be threated as open.
Ex:
Second output(output 1) of the Copy snap will be threated as open.
