Public bug reported:

Currently, the network cache assumes neutron is the source of truth for
which interfaces are actually attached to an instance. This is not
actually correct as nova is really the source of truth here. In order to
demonstrate this issue  if one creates multiple ports in neutron that
match the same device_id/instance_id as instances in nova those ports
will show up in nova list  even though they are not part of the
instance.
