Doom and Holy Freeze issue

Before I submitted this as a bug report, I wanted to get some verification and ask other members of the community if they’re experiencing the same things. I have a frost/cold zealot that is using Doom. I’ve noticed if I equip Doom with a Holy Freeze aura on, the damage calculates correctly with my own aura, but if I were to switch auras and go back to Holy Freeze, the damage gets recalculated wrong even though the radius of my Holy Freeze aura seems to be correct with my own skill level. Is this normal? What I would expect is that the damage calculation for an attack/zeal would use the ‘bigger’ aura in the end. On weapon switch to both Doom and my own Holy Freeze Aura, it also calculates correctly.

Bigger question is why are you using Doom with Holy Freeze?
