'Why new Airflow ( MWAA 2.0.2) nodes ( updated DAG ) can't be triggered from UI despite fulfilling dependencies

I have updated my DAG. Then I try to run new nodes. Referring to the picture below, one can assume the node highlighted is linearly dependent on just the node before.

DAGs

  1. I have clicked on the node to press run but it just return with no response. The setup is cluster mode ( not the local mode which disallow running from UI. This is MWAA, Amazon Managed Airflow Service, Airflow Version 2.0.2; Screenshot for running by ignoring dependencies.)
  2. I can run from UI for old nodes after clearing states
  3. New nodes have no states so we can't do 2.
  4. Scheduled run will work.

How can I trigger run of new node under this scenario?
