Bug blood barrier

Hello,
I have a sacrifice of blood active, i see the blood barrier icon but there's no numbers next to it. I have blood ans sand active but also the mastery to count as full life with 90% life. If i desactivate blood and sand i get blood barrier immediately.
I dont understand
thx

I have the same problem with auras but I am running petrified blood, tempest shield, purity of elements and vitality.
