WotLK 2P T9 Set bonus bug ?

[eri97]

Hey guys I just got my warrior 2 pieces of T9 set and I just saw the bonus saying that berserker stance gives 2% bonus critical strike chance but as shown on the photos I have 32.28% in battle stance and 37.28% on berserker stance which is only 5% by berserker stance itself. I even tried to relog thinking might be a visual bug or something still nothing changes. Am I wrong or is this bugged ?

Considering baseline berserker stance grants 3% crit i'm not sure what kind of bug you're trying to point out. 5% with 2p t9 is exactly what it should be.
