I have a similar problem that seems to be rather consistent:
With a custom format of "[%a %b]\{%n2 - %t - %a - %b}" I always get too many dashes:
Artist - Album1- - Trackname - Artist - Album.
Is there a mechanism for escaping or removing the dashes? What is the empty space in between the first set of dashes? Can you explain how the dashes and spaces are inserted?
THANKS!
