Cool Customer badge

The Cool Customer badge, "Defeat 50 of Crey's Cryogenicist bosses.":  are there some conditions in play that are not spelled out?   On my latest character, I've run the Manticore TF several times now, and although I've not made a clear count of the number of Cryo bosses each run, I'm quite certain my teams have arrested far more than 50, but my current count stands at 34, and I noted only a change of 5 when I checked in later.  I have done some Crey hunting in Bricks as well for the Numina TF, so I'm not sure if that 5 came from the Manticore TF or the street fighting.

 

Do I have to be the one to finish off the Cryo boss for it to count?  Do I have to "tag" it to count? Or is the team's victory over one sufficient?  It's just been very puzzling how the count slogs along while other kill counts ring up quickly in TFs.   Once I realized the slow pace, I started watching for boss tags in the Manti TF, and although I've not kept pace with my personal tally, there've been enough cryo bosses over the past several TFs that my count should be much higher, if not complete.

Should just be the Cryogenicist Bosses.  They're not that plentiful in Manticore with only appearing at levels 35+.   Dr Aeon's SF is where i've gotten the most.  Tip missions might be the other source.  Similar with Gamma Tanks.
