Sharepoint 2013 EE (installed not by me). What do I do:
Create new Web application
Create Site collection in it
Add Document Set Content type to default Documents library
Create new document set instance, set Name and Description fields
Open this document set properties (View all properties button)
Problem: Name field is empty. There's a column named "Name" in a left part of the window, but no column's value in a right part. On a Document Set Welcome page Name column's value is present.
