Why is there a velocity discontinuity next to a zero-velocity zone?

      I am modeling a pair of channels separated by a zero-velocity porous zone, through which only diffusion occurs. As you can see in this image, the flow profile is not parabolic, and has a velocity discontinuity. What can I do to have a continuous parabolic flow within both independent channels? I want to have a no-slip condition on the interface.

      Here are the membrane properties that I am using:
