Inserted file name comes with ? mark(version busting)

I am using waffle to upload images locally. The problem is generated file name has version bursting along with it

mix.exs

{:waffle, "~> 1.1.0"},
{:waffle_ecto, "~> 0.0.11"},

avatar.ex

defmodule MyApp.Avatar do
  use Waffle.Definition
  use Waffle.Ecto.Definition

  @versions [:original, :thumb]
  @extension_whitelist ~w(.jpg .jpeg .gif .png)

  def validate({file, _}) do
    file_extension = file.file_name |> Path.extname |> String.downcase

    case Enum.member?(@extension_whitelist, file_extension) do
      true -> :ok
      false -> {:error, "file type is invalid"}
    end
  end

  def transform(:thumb, _) do
    {:convert, "-strip -thumbnail 100x100^ -gravity center -extent 100x100"}
  end

  def filename(version, {file, scope}) do
    [name, _] = String.split( "#{file.file_name}", ".")
    "#{version}_#{name}"
  end

  def storage_dir(_, {file, user}) do
    "uploads"
  end
end

image.ex

defmodule MyApp.Common.Image do
  use Ecto.Schema
  import Ecto.Changeset

  use Waffle.Ecto.Schema
  schema "image" do
    field :active, :boolean, default: true

    field :image_details, MyApp.Avatar.Type

    timestamps()
  end

  def changeset(image, attrs) do
    image
      |> cast_attachments(attrs, [:image_details])
      |> validate_required([:image_details])
  end
end

image_controller.ex

defmodule MyAppWeb.ImageController do
  alias MyApp.Common
  alias MyApp.Common.Image
  alias MyApp.Avatar
  
  def multple_image_uploade(conn, params) do
    image_attached = params["image_attached"];
    {:ok, file_name} = Avatar.store({image_attached, _current_user = %{id: 1}})
    Common.create_image(%{image_details: image_attached})
  end

end

common.ex

defmodule MyApp.Common do
  alias MyApp.Common.Image
  def create_image(attrs \\ %{}) do
    %Image{}
      |> Image.changeset(attrs)
      |> Repo.insert()
  end
end
