Hi Ganesh! I looked into this more and it seems we purposely exclude certain fields such as date time, calculated fields, and others. Some of them are listed in the product documentation: https://www.servicenow.com/docs/bundle/xanadu-servicenow-platform/page/product/configuration-managem...
This is because typically we only want these fields to be updated by the correct authority. I see in your use case though, it's not as important as say last updated on field, but unfortunately that is just how it works currently. After remediation you can update them manually, or when the next payload comes for these items, make sure those fields are present in the payload.
