Aspect tooltip bug

I have 3 level 60 characters. I own a Arreat’s Bearing that shows a different aspect tooltip for all 3: Barb 42/85/42, Sorc 37/74/37, Necro 1405/2811/1405. There are some other pieces of gear that I’ve noticed the numbers being minuscule on my barb vs necro. Any reasonable explanation for that?
