Certain stuff can't have anointed ability

I know class mods and artifacts can’t be anointment but what I’m talking about is certain items. The 2 new guns from the new event can be anointed but I haven’t seen the new grenade and the new shield with them. Is that a glitch or not all weapons can be anointed? And I try to get The Ice Queen sniper anointed from Aurelia but still nothing. I’m just asking and wondering if I could be wrong.

i say its a glitch since the amara annointment “when grasping a enemy amara fires skulls at him” works in 1/10 cases. new items = new bugs.
