Incorrect JSON element tag in Document in IB

Dear All,

We are building a document to be used in IB. The document has collection and complex primitive. While testing the document through document tester, it is observed that JSON element tags are not coming correctly in collection section. It is picking the element tag of the root only or the document name, instead of picking the names for the collections or complex primitive for each respective individual sections.

Example taken from Peoplebooks: Here there is 'Contacts' {root}, 'ContactGround' {collection} and 'ContactsSupport' {collection}.

Instead of this, we are getting just 'Contacts' {root name/document name} throughout the Document structure.
