Janna heal (ult) not showing correct numbers when in possession of ardent censer

I assume this is the case with all of the new items that increase the heal, but anyways when I have ardent censer the heal value in one game showed 104 health when it was at rank 2 (I also had windspeakers so there was no way it would have only healed for 104). I don't know if the heal itself is reduced or if it's not showing the value that's actually being healed. This bug can be replicated.
