The title information shown in the update preview information is ambiguous.  Example:

In preview:

Title: Ghost in the Shell: Stand Alone Complex: Volume 4
Edition: not shown separately
Original Title (1): Kôkaku kidôtai: Stand Alone Complex: Volume 4
Original Title (2): Kôkaku kidôtai: Stand Alone Complex

After update:

Title: Ghost in the Shell: Stand Alone Complex
Edition: Volume 4
Original Title: Kôkaku kidôtai: Stand Alone Complex
Sort Title: Ghost in the Shell: Stand Alone Complex - Volume 4


Now, "Volume 4" should not be in the Edition field, but the preview looked fine.  There's nothing obvious in the preview to indicate that I should go back and check the profile for fixes.

There were two fields for Original Title in the preview, while there's only one such field in the program.  In many cases the second field is blank in the preview.  I'm not sure what each of them is supposed to represent, since the actual Original Title value seems like it can show up in either of the fields (per other updates I've looked at).

Requests:

Remove extra Original Title field.  If the second instance is supposed to represent something unique, label it as such.
Show Title separately from Edition.

Edit: Additional request -- on the Update Preview screen, the Produced field frequently indicates a change when the year remains the same.  I'm guessing that the change includes the country of origin.  Please include country of origin as its own field.
