   In your case they have the same value, it could be related to your 
[default-timezone](https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/timezone.html#default-time-zone).

   If you use `datetime.now()` for both parameters, there is a small chance 
that the scheduler processes the DagRun too fast because it's not overloaded, 
in this case, the two values could be equals.
   
   Using a variable date for dag `start_date` is a bad practice, and using 
`datetime.now()` as the value for that variable is worse. It would be better if 
you could use a fixed value, and if not, you can set it to `datetime.now() - 
timedelta(hours=1)` or `pendulum.yesterday()`. Could you test this before 
reopening the issue?
