Mass Fraction and Mole Fraction don't tie up

I have a case where a small amount of O2 (3e-10kg/s) is flowing into a system containing mainly air, the same amount of O2 is being sucked out of the system at another location. I am looking for the mole fraction of the O2 at yet another point in the system.
The model converges fine and if I display a mass fraction contour plot everything looks OK, i.e. I can see my mass fraction of O2 at the entry point is 1.
If however I try to display the mole fraction contour plot, the maximum value is approx 0.21, even at the entry where I know the mole fraction should be 1.
Has anyone got any ideas why the contour plots may not tie up and what I could try to solve this issue.
Appreciate your help.

how to determine mole and mass fraction in species part in boundary condition?
In my case, reaction between methane and air. I got the concentration value %vol/vol but I do not know how to convert it in term of mole and mass fraction.
Has anyone got any ideas? Thank you
