Scheduled runner never runs

GitLab CI/CD
1

Hi
I have set up a scheduled pipeline but it never runs
In addition the next run field seems incorrect.
I selected a Custom interval pattern
5 * * * * * which I understand means execute every 5 minutes
However, when saved it says it will be executed in 50 minutes

In my .gitlab-ci.yml I have

job:on-schedule:
only:
    - schedules
script:
    "/root/test.py"

build:
script:
“/root/test.py”
only:
- branches

Please can someone tell me where I’m going wrong

Thanks
