Light mode does not seem to work when specifying light / dark and time based images

[carcus88]

I am attempting to create an heic file that includes images light / dark and time based auto mode.

I am using the following JSON input

  {
    "fileName": "medsurvey-wallpaper-14inch-3024x1964_light.png",
    "isPrimary": true,
    "isForLight": true
  },
  {
    "fileName": "transition_1.png",
    "time": "2023-10-03T09:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_2.png",
    "time": "2023-10-03T10:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_3.png",
    "time": "2023-10-03T11:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_4.png",
    "time": "2023-10-03T12:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_6.png",
    "time": "2023-10-03T14:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_7.png",
    "time": "2023-10-03T15:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_8.png",
    "time": "2023-10-03T16:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_9.png",
    "time": "2023-10-03T17:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_10.png",
    "time": "2023-10-03T18:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_11.png",
    "time": "2023-10-03T19:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "transition_12.png",
    "time": "2023-10-03T20:00:00Z",
    "isPrimary": false,
    "isForDark" : false,
    "isForLight": false
  },
  {
    "fileName": "medsurvey-wallpaper-14inch-3024x1964_dark.png",
    "isPrimary": false,
    "isForDark": true,
    "isForLight": false
  }
]

My output from wallpapper -e is the following

Dark mode works find, auto mode works fine but when I select light mode in system settings the background is always using the time based background. I've tried the following

• Specifying time in the dark and light mode files in the JSON input. No change
• Only specifying the boolean values for light and dark mode in their respective options in the JSON input. No change
• Removing all the time based options. Light mode works but there is no auto mode as expected.

I have attached the heic file that is produced
