How do I add tracks to media #2?

When manually adding tracks to a double album (or any album that contains more than one item), you must tell CATraxx when you want to start adding tracks to the 2nd (or 3rd, 4th, etc.) media item.

To do this, simply choose Change Side from the Tracks menu in the 'Track Edit' window, then make sure the media item number you want to add the tracks to is specified, and click OK.
