New "ID" after grouping

When grouping, your "first level" changes. Without grouping, the first level are the file links you get back from your FROM/WHERE statement, so they automatically get displayed if you give no additional information to the LIST or TABLE command. The file link is the ID of your results.
After grouping though, your groups become the first level, the ID of your rows. That means without adding an additional information you'll see the groups in your list or table instead of the file links. To still see the file names, you need to pass them as your additional information to display per rows.file.link. Find out more about this in [[How GROUP BY works]]
