Thank you, Teknojnky.

Will be fixed.

using a filter that works fine as a playlist, does not seem to work on the album\unknown node.

filter:
status = accessible
path/filename does not contain \Misc\
path/filename does not contain \Unsorted\
path/filename does not contain \Podcasts\

returns 1236 files

playlist:
status = accessible
album is unknown
path/filename does not contain \Misc\
path/filename does not contain \Unsorted\
path/filename does not contain \Podcasts\

results in 1087 files
