   > I'm wondering why you use two schedulers. Are you using multiple headers for high availability?
   
   I did that because Astronomer actually recommends it for production: "To increase the speed at which tasks are scheduled and ensure high-availability, we recommend provisioning 2 or more Airflow Schedulers for production environments" As stated under the "Airflow Scheduler" section of his documentation: https://www.astronomer.io/docs/enterprise/v0.25/deploy/configure-deployment#scale-core-resources
   
   However, I don't have another reason to use 2 schedulers, I might switch back to 1. Nethertheless, it still is a sort of bug.
