Zero (0) loot from Anomaly boss

I've completed like 7-8 anomaly maps, with bosses that supposed to drop at least one support gem.

I had 2 maps so far, where boss did not drop anything at all.
Sealed Vault & Derelict Mansion. First map had 1 death, 2nd was death less.

Im playing poison PF with Headhunter, and usualy had HH buffs during fights.

Yes, i've held alt to check. There was literally no loot after killing bosses.

Same here,no loot from bosses at all,pressing ALT,loot filter disabled,ZERO loot,last map run was Sulphuric caverns.


P.S.
Running same PF poison build,could this bug be related to the poison DOT killing???
