Vile Knight Shielded Helmet not working

I spent a few minutes in close proximity to several rare monsters and bosses with my G tab opened looking at damage output and firing ocassional shots at the then seeing no change in my damage, with vile knight im supposed to be getting 4% increments per second which i clearly did not see. Plus I would love to see which buffs im being affected by: just like poe1. things like heralds would be nice to see active on me and also its support gems such as clarity and vitality.

Same

Im also not seeing any like debuff counter on the boss or at least the damage increase on my weapon while im in the presence of the boss. Not sure if its bugged or if they intended for it to not be seen.
