One of my views returns rentals where it’s status attribute is available, but it’s inconsistent in a way that there’s missing rentals on the view, even though they have the same available status

Checking the Console, it’s clear that there are more than one available car, even the first one is missing

 #<RentalCar:0x00007f211da1eb00
  id: 3,
  license_plate: "CCC3D44",
  car_id: 2,

  updated_at: Wed, 18 Sep 2024 21:13:03.386461000 UTC +00:00,
  status: "available">,
 #<RentalCar:0x00007f211da1e9c0
  id: 4,
  license_plate: "DDD4E55",
  car_id: 3,
  created_at: Wed, 18 Sep 2024 21:12:48.349913000 UTC +00:00,
  updated_at: Wed, 18 Sep 2024 21:12:48.349913000 UTC +00:00,
  status: "available">]

(license plate CCC… is missing):

This is the view using a simple conditional to list only available rentals

    <% if @rental_cars.present? %>
        <% @rental_cars.each do |rental_car| %>
            <% if rental_car.status == "available"%>
                <tr>
                    <td><%= rental_car.car.manufacturer.name %> <%= rental_car.car.name %></td>
                    <td><%= rental_car.license_plate %></td>
                    <td><%= rental_car.status%></td>
                </tr>
            <% end %>
        <% end %>
    <% else %>
        <td colspan="2">No rentals available</td>
    <% end %>

the missing rental had it’s status updated from this POST method in my orders controller:

  def return
    @order = Order.find(params[:id])
    if @order.status == "returned"
      flash[:error] = "Order already returned"
    else
      @order.status = "returned"
      @order.returned_at = Time.now
    end
    if @order.save
      flash[:success] = "Order successfully returned"

      # Changing rental status after saving the order
      @rental_car = @order.rental_car
      @rental_car.status = "available"
      @rental_car.save 

      redirect_to orders_path
    else
      flash[:error] = "Something went wrong"
      render 'show'
    end
  end 

I can’t figure out if the way I updated the the rental status is the culprid or the condition of the view.
