Why does Istanbul show coverage for everything in a promise chain regardless of whether or not there's a test for it?

My code has:

.then((data) => {
  let providerId = data[1].name;
  console.log(providerId);

  return global.db.Transcription.create({
    ConferenceId: foundConference.id
  })
    .then(() => {
      return {
        providerId
      };
    });
})
.then((dbTranscription) => {
  return factory.checkTranscription({
    Body: JSON.stringify({
      providerId: dbTranscription.providerId
    })
  });
})

Istanbul shows:

However, I have no specific test for the checkTranscription being called, etc. I'd rather not show that as covered. Is there anyway to do that?
