Custom fields per signer not showing up in document

[8vius]

I have 2 signers on my document template that each have some custom fields, I duplicate them because there seems to be no way to have common custom fields since DocuSign asks that you specify a signer for your fields

So I add these custom fields to each signer in my envelope request, but they don't show up in the document when I go view it.

custom_fields = {
      host_address: "Testing Host Address",
      host_civil_status: "Host Civil Status",
      host_id_number: "123HOSTID",
      host_tax_number: "123HOSTTAX",
      nomad_address: "Testing Nomad Address",
      nomad_civil_status: "Nomad Civil Status",
      nomad_id_number: "123NOMADID",
      nomad_tax_number: "123NOMADTAX",
      property_address: booking.listing.property.full_address,
      property_deposit: (booking.deposit * booking.price).to_s,
      property_description: "Property Description",
      property_start_date: booking.start_date.strftime("%d/%m/%Y"),
      property_end_date: booking.end_date.strftime("%d/%m/%Y"),
      property_stay_length: distance_of_time_in_words(booking.start_date, booking.end_date),
      property_montly_rent: booking.price.to_s,

    }
    @envelope = client.create_envelope_from_template(
      status: 'sent',
      email: {
        subject: "The test email subject envelope",
        body: "Envelope body content here"
      },
      template_id: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      signers: [
        {
          embedded: true,
          name: booking.listing.user.name,
          email: booking.listing.user.email,
          role_name: 'Host',
          custom_fields: custom_fields
        },
        {
          embedded: true,
          name: booking.user.name,
          email: booking.user.email,
          role_name: 'Nomad',
          custom_fields: custom_fields
        }
      ]
    )
