Ai Driven Value creation - showing complete Json Value instead of the specific count

I am new to Pyramid. I was doing Use Case7. While doing 'AI Driven Value Creation" to add " Show population for each country". It's showing the entire JSON value. How to resolve this and get the relevant population? 

Values: ```json
{
  0: {
    "value": 26000000
  },
  1: {
    "value": 38000000
  },
  2: {
    "value": 65000000
  },
  3: {
    "value": 83000000
  },
  4: {
    "value": 126000000
  },
  5: {
    "value": 126000000
  },
  6: {
    "value": 47000000
  },
  7: {
    "value": 67000000
  },
  8: {
    "value": 331000000
  }
}
```
