Applying song titles


Not sure if this is a bug? or if this can be improved on?
I have a few compilation discs that I need to apply song titles to from MusicBrainz
when applying to say disc 2, 3, 4 and 5 it takes ages for the list to go down to the correct track listing
it's hard to explain so I have taken a video recording of this issue.
now I have a lot of compilation discs to go through and this will take ages if this is how this works?

here is the link to the footage that i have recorded,
