Noted, thank you. We'll put it in on the to-do list and take a look at it when we have time.
Follow up: actually, there is a slightly sneaky way to work around this: add one or more non-breaking spaces to the end of the duplicate track name (ordinary spaces won't do it). To add a non-breaking space, hold down the Alt key and type 0160 on the numeric keypad. Of course, life can get a bit confusiong when you start typing in things you can't see...
