Are Annointed buffs supposed to be active even when using a different gun?

I have a sniper with 50% bonus incendiary damage on action skill end equipped. I’m using a brainstormer with corrosion action skill damage and 5/5 infusion. I should see blue and green numbers and I do. Upon action skill end, I still see the same blue and green numbers, barely doing any damage to human targets. No red numbers.

Is the PS4 version of this game bugged? I thought annointed bonuses are all active on all equipped gear. That explains why I’m not seeing other annointed bonuses such as 250% weapon damage after phasecast.

Aww crap. Well that sucks then. Many of these build videos rely on finding the right anointed buff on the right gun.
