Hi. I want to use the Github Action cron schedule to run my jobs.
My workflow YAML is as follows:

ame: App CI

on:
  schedule:
    - cron: "20 1 * * *"
    - cron: "25 1 * * *"
  

jobs:
  update-hpa:
    name: Update tmp yaml
    runs-on: ubuntu-latest
    strategy:
      matrix:
        schedule: 
          - name: "10h20m"
            cron: "20 1 * * *"
            value: "50"
          - name: "10h25m"
            cron: "25 1 * * *"
            value: "70"
    steps:
      - name: Checkout Repository
        uses: actions/checkout@v4

      - name: Print Matrix Variables
        run: |
          echo "Schedule Name: ${{ matrix.schedule.name }}"
          echo "CPU Value: ${{ matrix.schedule.value }}"

But, even with this configuration, I noticed that the Github Action does not run at 1:20 AM or 1:25AM UTC, nor at any other time I checked. Even whe I configure it like */5 * * * * to run at regular intervals, it doesn't run every 5 mins as intended. Is there a bug causing this issue?
