I am editing:
Disc 7 has 14 tracks. When I originally added this medium to the album, I followed the booklet, thus the medium was created with 13 tracks. Unfortunately, the booklet is wrong: the disc has 14 tracks!
I made an edit to correct this, but, after a week of waiting, it failed 
I have now created yet another edit with the same correction:

I am concerned that it, too, will fail, as it is exactly what I had entered the first time. How can I get this done right?
