One Blue Iris MQTT Motion image is working, other is not

I have one camera in Blue Iris that when motion is detected, sends an alert image to Home Assistant via MQTT. It works great

The Blue Iris mqtt alert settings for this camera is:

This one for the drive way does not:

Please note that these two cameras that stream to Blue Iris are the exact same model.

Here is the configuration.yaml for these mqtt cameras:

mqtt:
  camera:
    - topic: "blue_iris/dw/alert-image-b64"
      name: "Driveway Alert"
      unique_id: camera.dw2
      image_encoding: "b64"

    - topic: "blue_iris/fl/alert-image-b64"
      name: "Front Yard Alert"
      unique_id: camera.fl2
      image_encoding: "b64"

Again, the Driveway is the one that does not work.

On my dashboard,
This works for the front left camera:

show_state: true
show_name: true
camera_view: auto
type: picture-entity
entity: camera.front_yard_alert

It will show an image of the “movement” that triggered the motion alert.

Here is the code for my driveway image alert:

show_state: true
show_name: true
camera_view: auto
type: picture-entity
entity: camera.driveway_alert_2

When motion is detected, the image will go from unavailable to a dark screen:

If I change the unique id for the driveway camera, a second entity (camera.driveway_alert_2 is created as you would expect and therefore I have to use:

show_state: true
show_name: true
camera_view: auto
type: picture-entity
entity: camera.driveway_alert_2

So I say that just in case someone might think I am using the wrong entity for the camera. I go to the mqtt integration to find the new camera entity name.

Regardless, my problem is one camera works and the other does not. I have tried my best to ensure each camera is configured exactly like the other in Blue Iris and I cannot find a difference in Home Assistant.

When I start over each time, the driveway camera image is shown as unavailable until the first alert is sent from Blue Iris. At that time, the image becomes a black screen.

Does anyone have any ideas on why the Driveway one is not working or how I can troubleshoot further?

Thanks!
