Whenever I use the BiS (and occasionally the BiB) it does not actually update what the BiS are and shows me my own gear as if it were BiS (I know for a fact that it is not)
It also appears to not recognise that the stones in my annulet are max level
EDIT:
Figured out the issue, the min and max item level for some reason had 0 and 0 value in it causing it to not do anything. Emptying the fields resolved this.
