Are you sure you want "GROUP" and not "SECTION"? (same for GR-Lot)
Just to make sure before we patch everywhere ...
In the NTDs I can see things like:

"id" : "GR-Lot",
    "contentType" : "group",
    "nodeId" : "ND-Lot",
    "displayType" : "SECTION",
    "description" : "Lot related information covering Tendering Terms, Tendering Process and Purpose",
    "_label" : "group|name|ND-Lot",
    "_idScheme" : "LOT",
    "_schemeName" : "Lot",
    "_identifierFieldId" : "BT-137-Lot",
    "_repeatable" : true,
    "content" : [ {
      "id" : "BT-137-Lot",
      "contentType" : "field",
      "displayType" : "TEXTBOX",
      "description" : "Purpose Lot Identifier",
      "_label" : "field|name|BT-137-Lot",
      "_idScheme" : "LOT",
      "_schemeName" : "Lot",
      "hidden" : true
    }, {

Ok so apparently this is on purpose for the GROUP.

Looks OK.
