Pressing the YAML check configuration button often results in a green “Configuration Valid” result but errors are logged and persistent notifications about theses errors are created.

This sounds like a bug report and needs an example.

Using this invalid trigger:

  trigger:
  - platform: time
    state: "00:00:00"

Passes config check:

And I agree, it is an issue report rather than WTH. Closing.
