Game Mechanics: Mage Bandages, change intentional?

[T7g]

A while back there was a change to the summon bandages spell that always only gave me 5 bandages instead of the 20 I should be getting cause of level. I figured it'd get fixed on it's own but for a while now I have to cast summon bandages four times to get a stack, is this intentional? If not, I can confirm a level 50 mage is only summoning 5 bandages per cast.
