Warrior Damage conversion bugged with Avatar of Fire

Damage decreased around 30% after new patch, it seems like damage conversion on Avatar of Fire is somehow missing part of the fire damage bonus (I had around +370% fire damage bonus). Can someone explain?

after update:
hammer of god damage from 300k to 200k
stampede damage from 12k to 8k

For example, with stampede (without fire damage gem):
(all calculation in lowest damage)

Before:

without avatar of fire:
total damage: 4873
physical damage: 2755
fire damage (i have +fire damage to attack): 2188

with avatar of fire:
total damage: 7862


now:

without avatar of fire:
total damage: 4123
physical damage: 2755
fire damage (i have +fire damage to attack): 1368

with avatar of fire:
total damage: 5077

update: the damage shows normal sometimes in town

Found out the problem: the soul core of citaqualotl (+element damage) works abnormal after new patch with damage conversion.
