Test --cover not changing despite adding test?

I’m having trouble understanding how test --cover is working. I see a module has 0% coverage, add a test for the function defined in that module and test --cover still says 0% for that module. Also, not sure why it is flagging some functions not defined in the module as needing tests. Here is an example of what Im talking about:

here is a screenshot after running test.coverage:

here are the tests for it:

defmodule Core.Tenants.Settings.CheckoutTest do
  @moduledoc false

  use ExUnit.Case, async: true
  alias Core.Tenants.Settings.Checkout

  @valid_attrs %{asset_key: "some string"}
  @invalid_attrs %{}

  test "changeset with valid attributes" do
    changeset = Checkout.changeset(%Checkout{}, @valid_attrs)
    assert changeset.valid?
  end

  test "changeset with invalid attributes" do
    changeset = Checkout.changeset(%Checkout{}, @invalid_attrs)
    refute changeset.valid?
  end

  test "asset_key is required" do
    changeset = Checkout.changeset(%Checkout{}, Map.delete(@valid_attrs, :asset_key))
    refute changeset.valid?
  end
end
