Display Name in PO need to be removed

Display Name in PO need to be removed

Frequently we've created a PO to vendor and drop ship to customer. 
Billing and Shipping Address are different Name
Whenever we created a PO and it shows contact display name, attention and company name
which is confusing for receiver.

PO template does not have ${CONTACT.CONTACT_DISPLAYNAME}

Here is the Example

Billing Address: 
John Doe
CBDCompany
5555 Main St
New York, NY 11111

Shipping Address
Jane Brown.
ABC Company
1234 Main St
New York, NY 11111

In Zoho Contact
Primary Contact: John Doe
Company: ABC Company
Contact Display Name: John Doe

Billinig and Shipping Address tab same info above

When I created A PO and Deliver to address shows;

John Doe  <---- DISPLAY NAME CAME UP. 
Jane Brown. 
ABC Company
1234 Main St
New York, NY 11111

I've tried two Zoho books account and it does the same.

Please advise

Thank You
