Column Formatting and View Formatting JASON

Dear All

I am currently working on the SharePoint List Column Formatting and View Formatting. Basically I just copied the JSON code from someone else (his working perfectly) but mine have the following issues:

1. Date is not showing
2. Approvers' yellow/ green/ red light is not show (only showing the circle without color)
3. Approval status doesn't show status of new/ pending/ approved as well as color and the timeline stay at finish line even the flow just started
4. Approval history is not showing

Mine (incorrect):

Should be like this (correct version):

I do not know what went wrong as I just copied the entire JSON. Can someone help?
