Bug in "Modify Complex Invoice and Shipment Payloads Simultaneously" Problem

[f-schnabel]

My solution works both in the official dataweave playground and also the DWCode playground but when executing my solution in the Problem it returns another result:

Expected Output:

{
  "refId": "R1",
  "invoice": {
    "invoiceNo": "INV001",
    "status": "POSTED",
    "amount": 500,
    "postedDate": "2024-01-01"
  },
  "shipment": {
    "shipId": "SHP001",
    "trackingStatus": "IN_TRANSIT",
    "weight": 5.5
  }
}

Actual Output:

{
  "refId": "R1",
  "invoice": {
    "postedDate": "2024-01-01"
  },
  "shipment": {
    "shipId": "SHP001",
    "trackingStatus": "IN_TRANSIT",
    "weight": 5.5
  }
}

If you need the exact code from my solution I will add it as a comment
