Corvus getting bleed from node on AQ

Mist

Last night, I was fighting Ant man on bleed node in AQ map 3 last section. My Corvus was unexpectedly bleed from the node even though he had fully 20 Glaive charges atm. I though he was bleed immune when his Glaive charges available.
P/s: I’m using iPhone 7 Plus and IOS 11.3

He does get the bleed debuff but doesn’t take damage from it (so he will actually heal with WP on).

I know about that, but in my case he was actually bleed. I was at 15% heath and bleed to death from the node.
