Name Series and Voucher Type

I have noticed that the the credit memo’s do not have their own naming series , it uses the same naming series as sales invoices , also after submitting the Sales Credit Note , the ledger shows as sales invoice and not Sales Credit Note or Sales Return.
Goes same for Purchases.

Using Frappe 12.15.0 , ERPNEXT 12.13.0

Also the print view shows as Sales Invoice and not Sales Return or Sales Credit Note.

TO RECREATE THIS ISSUE -
Create a sales invoice , submit , then process a sales return.
You will see that the customer ledger shows as sales invoice as well as the print out.

Is there a way to show this as a Return on the ledgers and print ?
