@LegionMammal978 HEY, it's another code-golfer (note, this room gets little activity)! I noticed that the consonants that appear at all frequencies, /vðzʒfθsʃ/ are all fricatives. The others (/mnŋlɹw/) are not, and are also all voiced. Maybe that has something to do with it? The voicing might explain why /h/ and /ʍ/ you are not really sure about. Also, /j/ is the only palatal sound there, so that might mean something. But I have no clue as to why, however.
