Why the expb does not match odds ratio?

Hi there,

I am trying to get odds ratios from PROC LOGISTIC procedure. But the result of exp(estimate) does not equal to the odds ratio tables. See my result attached. And my code is

proc logistic data=master4;
class race_flag(ref='1');
model regret_flag (event='1')=race_flag/expb;
run;

Thank you.
