Child data groups XML tags are not generating in HCM Extract while email bursting

Summary:

We are using HCM Extract and created a BIP report to place the report in DOR and Email bursting. Now when we run the extract, the extract xml is generating data for all the data groups, we used one parent and 2 child data groups and data in xml output is present in all the data groups.
But when the email bursting or DOR is triggered the xml generated by the BIP report is showing only the parent data group and all the child data groups are missed. Due to this we are not able to see the total data in the report.
