Weird because it works fine for me (Win 10).
It will list Title Id and Build Id for NSP/XCI. Which is nice to know pre hand as to which cheat file you will need, per build id.
To find the Build ID of a nsp:
Load nsp in FileViewer, select "content" tab, select game "program" file, "section 0", then "main". Build Id/module id will be the first 16 number listed at bottom of page.
