I think there was a time when Formats could be shown as a column (i.e what you see in Book Details Formats), but because it created performance problems the approximate_formats() function was provided, either then or later the support for Formats as a column was dropped.

Maybe the OP's Formats column is an artifact of an earlier version of calibre
