Reservation type who is not define is show in the Highlight section

Question

I have recently add the json data to an email for show the highlight section in the email client for a train reservation but in the email there are also a advertising section for a care hire company and it's show this in the highlight too.

Is there a way to disable the RentalCar type in the email or to indicate to indicate to the client to ignoring a specific section of the html?

JSON-LD example

{
"reservationNumber": "XXXXX",
"reservationFor": {
  "trainCompany": { "name": "Company", "@type": "Organization" },
  "departureStation": { "name": "Departure station", "@type": "TrainStation" },
  "arrivalStation": {
    "name": "Arrival station",
    "@type": "TrainStation"
  },
  "arrivalTime": "2018-08-15T12:47:00",
  "@type": "TrainTrip"
},
"price": "10.00",
"reservationStatus": "http://schema.org/ReservationConfirmed",
"checkinUrl": "https://checkin-url.com/uk-en",
"modifyReservationUrl": "https://checkin-url.com/uk-en",
"@content": "http://schema.org",
"@type": "TrainReservation"}

Thanks
