Default Multiphase simulation-Very high pressures

Hass is on a distinguished road
I'm doing a simulation of air-water bubbly flow in a horizontal pipe.
Eulerian, standard k-e (y+=220)
B.C.s-Velocity inlet, Pressure outlet(0 gauge)
First order upwind
My problem is that when I plot/report the static pressure along the pipe centerline, I get very high values (around 1e11 Pa) at the inlet and it reduces to 0 at the outlet. The dynamic pressure for each phase is much more reasonable at around 1000 Pa. What could be causing the pressure to float so much? Do the reference values affect the value of pressure?
