Suppose I am backing up a certain directory, and the backup tape becomes filled up, so I put in another tape.
Then at a later time I wish to restore that directory, so I create a restore job. If I select that single directory that was backed up, only the first backup tape displays in the lower window. Both backup tapes should be displayed.
If I drill down to find the files underneath that directory that were backed up to the second spanned tape and I select that file, then the second tape is displayed in the lower window.
Bottom line: Whatever directory or directories I select in a restore job, ALL tapes containing files in that directory or directories and all subdirectories should be displayed.
