Notification sound file setting not honored consistently

Mobile Apps Home Assistant Companion for Apple
1

I have a number of automations that push notifications to the app with sounds specified. I am using both the iOS app built in sounds and some built in ones downloaded from iOS. They all work fine.

I recently set up some Frigate camera notifications using Sgt Batten’s blueprint, and the notification event works perfectly calling a built in sound for one event, but not for another. On the nonworking one (garage), I had originally set it to US-EN-Alexa-Motion-In-Garage.wav, but once I realized another alert was working with the correct sound (back door), I changed the garage one to US-EN-Alexa-Motion-At-Back-Door.wav to see if it was an issue with the filename, but the garage alert is still only playing the default sound.

These notification automations are duplicates of each other, with the only difference being which Camera is indicated in the setting.

Here is an example of the working one:

alias: Back Door Camera Alerts to Nate
description: ""
use_blueprint:
  path: SgtBatten/Stable.yaml
  input:
    presence_filter:
      - ""
    camera:
      - camera.back_door
    notify_device: 76b2d883c92faa97530e597cf0cabb60
    message: A {{label}} was detected on the back door camera.
    alert_once: true
    review_severity:
      - alert
    cooldown: 10
    sound: US-EN-Alexa-Motion-At-Back-Door.wav

The one playing the default sound is the same, the only difference being the alias, camera, and message:

alias: Garage Camera Alerts to Nate
description: ""
use_blueprint:
  path: SgtBatten/Stable.yaml
  input:
    presence_filter:
      - ""
    camera:
      - camera.garage
    notify_device: 76b2d883c92faa97530e597cf0cabb60
    message: A {{label}} was detected on the garage camera.
    alert_once: true
    review_severity:
      - alert
    cooldown: 10
    sound: US-EN-Alexa-Motion-At-Back-Door.wav

Since it uses a blueprint, when I view ‘Automation config’, they are both 1068 lines of YAML, and a text comparison in Notepad+ shows them as identical other than the camera names where they appear.

I have closed and reopened the app, pulled down on it to refresh, and reset the frontend cache at this point.

I even deleted the garage one, re-duplicated the working back door one to a new garage one, and then edited just the camera and nothing else, and it still plays the default sound.
