See Letting through MIDI events.

Matched events

If checked, even MIDI events matched by at least one mapping are let through. If unchecked (default), such events are filtered out.

Unmatched events

If checked (default), MIDI events that are not matched by any mappings are let through. If unchecked, such events are filtered out.

Check out Match even inactive mappings to fine-tune matching behavior.
