Round-to-even results in an odd number instead of even ?

Question

131.505 => 131.5
131.515 => 131.51 <- wt*
131.525 => 131.52
131.535 => 131.54
131.545 => 131.54
131.555 => 131.56
131.565 => 131.56
131.575 => 131.57 <- wt*
131.585 => 131.58
131.595 => 131.6

I was expecting
131.515 => 131.52
131.575 => 131.58
