How to calculate the production rate of some surface reaction in FLUENT?

Hi~

I built up s model using Finite rate/Eddy dissipation with surface reaction.
The surface reaction is calculated using Arrhenius rate. The option for Mixing rate is blocked an turned grey in setup window.

I found that "Rate of Reaction" is zero, "Kinetic Rate of Reaction" is a non-zero value, and "Turbulent Rate of Reaction" is zero, using "Report→Contours→Reactions...".
Another strange thing is that the contour of mass fraction of this reaction product is not zero.
The value is 1 on the wall.
However, I don't know how to calculate the produciton rate.
Could anyone kindly help?
Thank you!
