@peterzhenhh: I've updated the script again to improve handling of packages with audio assets. You may report multiple issues at once by providing only names of packages, if it's the same error type. Just make sure you've converted original packages again with the updated script before submitting possible issues.
Thanks a lot. Through a full test, only the following packages have wrong name index errors. But this doesn't affect the export of audio

UTEditor.u
UTGame.u
Core.u
GFxUIEditor.u
TPAITrng.u
TPSRelaxingZone.u
UnrealEd.u
