[Bug] Artist Filter is not working correctly

Unless I’m really not understanding how this filter is designed, there is a bug within the Filter in Plexamp. I am not able to achieve the results I’m looking for.

I have Filtered by Artist Genre of “Punk” and Style ‘Is Not’ “Old School Punk”. Then added a Group, and Filtered by Artist Genre is “Pop Punk” but it filters down to 1 artist. My understanding is that when you Add Group, it should be looking at a new sun set of data? If this is not how it works, how can I achieve what I’m looking for? (Punk, that is NOT style Old School Punk, then also include Pop Punk)

I think what you want is:

MATCH ANY
  Genre is Pop Punk
  MATCH ALL
      Style is not Old School Punk
      Genre is Punk
