Hi @vamsi_simbus ,

Try to use rest api to delete policy. Once you do that, delete additional row filters and once again create ABAC policy.

Delete an ABAC policy | ABAC Policies API | REST API reference | Databricks on AWS

Or try to drop it using SQL;

DROP POLICY <policy_name> ON <securable_type> <securable_name>

If you can't - ask your admin to execute above command for you
