electroosmotic flow profile in comsol

Hey all:

I am trying to simulate electroosmotic flow in microfluidic channels. My electroosmotic flow does not look normal and it has a higher velocity close to the wall and a lower velocity in the center of the channel. Theoretically, the electroosmotic flow should have a flat profile. I checked everything with the old comsol library model "electrokinetic flow in biochip"3.5a and also a youtube video online about biochip simulation in a more recent version. Everything in my simulation looks ok but the flow profile looks weird.

Does anyone know why the ellectroosmotic flow is not a flat profile in comsol or I messed it up? I attached my mph file here just in case if anyone wants to see it.

Thanks!
Best reagrds
