Issues are listed in numeric order (latest issue first) instead of grouping with issue type (fault, test case etc.) in Release Notes under Release Board within Agile

When creating release notes using Agile release note under Release Board, It seems that issues are listed in numeric order (latest issue first) instead of grouping with issue type (fault, test case etc.)
And also from the attachment,you could see that the issue type of Fault display as two different groups twice.
