Zoho Creator's v2 API GET Record - Detail View Missing Fields

Zoho Creator's v2 API GET Record - Detail View Missing Fields

As the Title said. 

I tried to use Flask request.get() and Postman and both of them only showing a some of the fields availiable.
It seems it's showing what's in the Overview and not real Detailed data fetching. How can I get this field? 
I feel Detailed View should show all the field in it and not just an Overview.
