@odata createdAt Null values

[damovand]

Following Create an SAP Fiori Elements-Based UI | Tutorials for SAP Developers the Fiori list page was missing several data items. The root cause is missing data items. In the following I found null data for createdAT and incorrect data for modifiedAt which seems to have shifted all values. The $metadata is correct, just not the values that should be coming from some oData library! Any ideas what might be the root cause?

{"@odata.context":"$metadata#Risks","value":[
