Bleed vulnerability node issue in lab

Lrrrr

Wish i had a screen shot but i fought spider gwen in labs on bleed vulnerability node (200%). She ticked off 291 every half second from Blades parry bleed. Fought she hulk next fight and her bleed damage was exactly the same with armor node from blades parry bleed. It was on the lowest difficulty quest of lab.

I think the way bleed vulnerability works is that you do the increased damage only when the opponent is already bleeding.
So, the first parry in the fight(when the opponent is not currently bleeding) will do normal damage. You will get the increased damage if you parry again while he is bleeding.
