Unexpected __data in mongodb loopback v3

Why my database has field __data that exactly copying the real data but wouldn't update if the data is changed?

Here is the example of the data :

{
  "id": ObjectId("600ffdf0317f9617960b7df6"),
  "userId" : "bf959bb8-78a6-426b-b372-cf5a1f9ef731",
  "name": "Product 1",
  "isActive": true,
  "createdAt": ISODate("2021-05-26 11:33:04.992Z"),
  "updatedAt": null,
  "__data": {
    "id": "600ffdf0317f9617960b7df6",
    "userId" : "bf959bb8-78a6-426b-b372-cf5a1f9ef731",
    "name": "Product 1",
    "isActive": true,
    "createdAt": ISODate("2021-05-26 11:33:04.992Z"),
    "updatedAt": null,
  },
}

when I update the data lets say, {"name": "Product 1 New"}, but the "__data.name" still "Product 1"

The problem is when I get the data using find() or findById(), the result is showing "Product 1" which is get from the __data instead of the real data.

I'm using loopback v3 and using mongodb for the database. Below is my schema for product.

product.json

{
    "name": "products",
    "base": "PersistedModel",
    "plural": "products",
    "idInjection": true,
    "options": {
      "validateUpsert": true
    },
    "properties": {
      "id": {
        "type": "string",
        "id": true
      },
      "userId": {
        "type": "string"
      },
      "name": {
        "type": "object"
      },
      "isActive": {
        "type": "boolean",
        "default": false
      },
      "createdAt": {
        "type": "date",
        "default": "$now"
      },
      "updatedAt": {
        "type": "date",
        "default": "$now"
      },
    },
    "validations": [],
    "relations": {
      "user": {
        "type": "belongsTo",
        "model": "reseller",
        "foreignKey": "userId"
      }
    },
    "acls": [
      
    ],
    "scope": {
      "order": ["createdAt DESC"]
    },
    "methods": {}
  }

How to solve this?

I want to get the response is the real data which is the updated one, and how to avoid to have field __data?
