some issues on the paper 'Numerical Simulation of Oil Recovery by Polymer Injection using COMSOL' (Revised)

In this paper, the transport of polymer and salt species is simulated in the Module 'Transport of diluted species in porous media' . In this module, symbol εp denotes porosity, but the mathematical model indicates it should be 'Φ(porosity)×Sa(saturation of aqueous phase)'.
Here, I attach two images of the aqueous phase saturation (Sa). From the graphs, after 350d, Sa will exceed 1, which is not consistant with the changing law of saturation. While Cs (concentration of salt) comlpies with the paper.
Does anybody else has met this situation? If you do, please contact me or share some ideas with me.
Sincerely
