Identities split into multiple resources doesn't seem to work

Not sure if I'm doing something wrong, but I have 2 resources that uses the same table, User and Customer. In my User resource I have these identities: 
  identities do
    identity :unique_email, [:email] do
      eager_check_with FeedbackCupcake.Accounts
    end

    identity :unique_referral_code, [:referral_code]
  end
  identities do
    identity :unique_email, [:email] do
      eager_check_with FeedbackCupcake.Accounts
    end

    identity :unique_referral_code, [:referral_code]
  end
And in my Customer resource, I have these identities: 
  identities do
    identity :unique_customer_id, [:customer_id]
  end
  identities do
    identity :unique_customer_id, [:customer_id]
  end
For some reason, Ash just adds the indexes for the User resource in my PostgreSQL table, the one in Customer is simply ignored and doesn't show up in the migrations at all.

all the usual stuff i.e: added to the registry? api added to the ash_apis key in config?

Does customer have a customer_id attribute? Perhaps you mean :id?

Yes, the resource is added to the registry and the api is added to ash_apis, it is not that the resource itself is being ignored, all of its changes (new attributes, etc) are being correctly applied in migrations, just the identities that are not. Yes, the Customer has a customer_id attribute, User does not: 
    attribute :customer_id, :string do
      constraints max_length: 255
    end
    attribute :customer_id, :string do
      constraints max_length: 255
    end
Not sure if this helps, but this is the Customer resource code: 
defmodule FeedbackCupcake.Payments.Customer do
  @moduledoc false

  use Ash.Resource,
    data_layer: AshPostgres.DataLayer

  code_interface do
    ...
  end

  attributes do
    alias FeedbackCupcake.Payments.Customer.PaymentMethod

    alias FeedbackCupcake.Ash.Types.Currency

    uuid_primary_key :id

    attribute :email, :ci_string do
      allow_nil? false

      writable? false
    end

    attribute :first_name, :string do
      allow_nil? false

      writable? false
    end

    attribute :surname, :string do
      allow_nil? false

      writable? false
    end

    attribute :customer_id, :string do
      constraints max_length: 255
    end

    attribute :payment_method, PaymentMethod

    attribute :balance, Currency, allow_nil?: false, default: 0

    timestamps()
  end

  relationships do
    alias FeedbackCupcake.Payments.Subscription

    has_one :subscription, Subscription
  end

  calculations do
    calculate :full_name, :string, expr(string_join([first_name, surname], " "))
  end

  preparations do
    prepare build(load: [:full_name, :subscription])
  end

  postgres do
    table "users"

    migration_ignore_attributes [:email, :first_name, :surname]

    migration_types customer_id: {:varchar, 255}

    repo FeedbackCupcake.Repo
  end

  identities do
    identity :unique_customer_id, [:customer_id]
  end

  actions do
    ...
  end
end
defmodule FeedbackCupcake.Payments.Customer do
  @moduledoc false

  use Ash.Resource,
    data_layer: AshPostgres.DataLayer

  end

    alias FeedbackCupcake.Payments.Customer.PaymentMethod

    alias FeedbackCupcake.Ash.Types.Currency

    uuid_primary_key :id

  end

  calculations do

  end

That needs to add up all of the identities on all snapshots, just like it does for other things. I’m in the car, but if you want to PR a fix ill merge it
