From SE80 itself it's not showing the drop down list values. In standard this component configuration is not having these all fields, it's having IFSC code, Disability, Health fields. We did enahcne and added the required fields as per IT0185. All field properties/attributes are fine for this field ISCOT If you see my 2nd screen shot in my initial post.
We are using EHP7.
