FlinkOperator's state not working as expected

I submitted wordcount and other jobs..

I was expecting state flows as follow:

New --> ClusterStarting -> Running

But, When I see in UI, the job as finished already but in operator events it never showed ClusterStarting and Running...
Then, Running to Updating
Updating to ClusterStarting

From Running State, I was expecting it to go to Updating State. But all the logs show is SubmittingJob

On minimum from SubmittingJob to Running should have be captured right?

Logs:

Start with the operator's state-handling and reconciliation path, using the provided kubectl logs and the transitions around ClusterStarting, SubmittingJob, and Running. Investigate the status-update conflict and repeated SubmittingJob handling. Done means the expected state transitions are reflected in operator events and the job no longer remains in SubmittingJob unexpectedly.
