You have a problem with concentration as it's linked to the cell volume. Whilst the solver is working as intended you're then getting some results that are a little confusing: the inlet area, parcel mass etc make interpreting the results difficult. Plotting DPM MASS might resolve the issue as it may be more uniform/distributed and avoid looking at 3D. Note, I can't remember how Fluent calculates cell volume in 2d-axi so plot the value and see how it's accounting for the swept volume.
