Death caused by knockback

I tried a duel againt Zikell and the knocked back state still causes death because he pushes me under texture i dont know, because when he used the skill Soul Crush II that triggers for chanters after you are stunned, it puts you in a knocked back state. I know its geodata problem, but to be sure its reported. I think same issue is with the dragon bosses (spallers) in DP, those used to knock you under texture. And the heals Carl and devs added after duels doesnt matter this time because u just instantly die. whatever your hp is.
