I've just gone into Mezzmo to do a few tweaks after a stable period.

Call my main listing "Subjects". Under Subjects I have a variety of types of menu entry - e.g. Action, Clint Eastwood, TV Shows, and Next To Watch.

Outside of Subjects I have menu items including Home Movies, Years and Top 50.

When I go into a Subject to modify the filter, all of the settings are blanked out, except Change Artwork. On every Subject.

When I go into a playlist which is outside of Subjects, I can change the filters as expected.

Is it me or a bug?
