Notification Scheme Notifications and Project Settings - Customer Notifications

JIRA Version: 7.3.2

Service Desk Version: 3.3.2

We already have our defined Notification Scheme for the Service Desk Project like who should be notified on which transitions of the Issues. After updating to JIRA 7.3.2 we have also set up some Customer Notifications in Project Settings of a Service Desk Project. But it looks like Service Desk agents/ Internal Customers are also getting the emails which are being set from the customer notifications tab on Project level. 

It is not easily traceable when the Notification Scheme is coming into picture and when the Customer Notifications on Project Level are being used to sent the email Notifications.

We also have one Approval Workflow where we would like to have the email sent to other approvers when one approver approves or declines the Issue. Selection of Approvers is being done on the post function of one of the Transition according to the Organization Structure. Even if this is explicitly included in a Notification scheme other approvers does not get any email on the updation of the Issue. Also took help of Notification Helper and it says that other Approver should be notified for a particular transaction ( Approve / Decline). 

Would like to have a suggestion, how to go further with these Email Notifications?

Thanks a lot in advance.
