Apache Airflow version

What happened?

I executed the following command to backfill Airflow DAGs:

airflow dags backfill -s "$current_date" -e "$next_day" "$DAG_ID" --reset-dagruns However, I encountered several issues:

I cannot clear tasks from the Airflow UI. If the backfill process is interrupted or killed, I cannot restart or resume the DAG from the UI.

What you think should happen instead?

How to reproduce

Run the backfill command:

airflow dags backfill -s "$current_date" -e "$next_day" "$DAG_ID" --reset-dagruns Check the Airflow UI:

Attempt to clear tasks and verify if the option is functional. Try to restart or resume the DAG if the process is killed.

Verify that this issue persists, but note that it wasn't introduced with 2.10.rc1; it also existed in 2.9.3.

I have also experienced this issue. After tasks were backfilled and then cleared over the same time period, a clear does not initiate queuing of the tasks. Note that this existed in both 2.8.1 and now in 2.9.2 in MWAA.
