Drop Ship section of "Purchase Order" broken in v13?

I see in Customize Form > Purchase Order there is section for “Drop Ship”…

Consisting of customer, customer name, contact, mobile, email, etc…

but this section is missing from my “New Purchase Order” screen (should be above “Address and Contact” section?)…

Maybe… this section only displays when a linked drop ship enabled SALES ORDER exists?

I have watch several youtube videos looking for this “Drop Ship” section above “Address and Contact” and it is always missing. So probably it is not a bug… I just don’t know how to use it.
