In Jaikoz 4.0.0 whenever I do a manual correct metadata from Musicbrains the match found always has the track no the same as the # tracks field.
To recreate this just do a manual correct of an already corrected track. You will see that when the source track is no 6 from 16 for example the found match is then 16 from 16.
On a sidenote, the # tracks that is already in the source track is also not shown in the manual correct result window
