Changes in the description settings under project settings are not applied to the packaged version of the project.
Tested in: 4.22.3 CL#7053642, 4.24 CL#10091930 4.25CL#10183780
Results: The fields that were changed under "Description" in project settings are not applied to the packaged product. the "Display Name" section is displayed in the Task Manager, however, it is under the default "UE4Game"
Expected: The altered fields to contain the same information after packaging the project
