Part data miss match in ESI released xml

I am using Windchill Enterprise Systems Integration Release 11.1 and Datecode with CPS M020 CPS29

Data miss match in released esi xml, Modifing the existing parent BOM and releasing through ECN after completion while validating the xml all the child components data are showing under changed tag in part section and in the component section components are showing as unchanged components.

Here are the errors that I faced
No error message, some of the BOM data is showing wrong in the xml
