Default setExprFields changing the BC

I wanted to provide hydrostatic pressure under a wave profile as an initial condition. I decided to use the setExprFields method.

My setExprFieldsDict looks like below
readFields ( alpha.water );

target value;
expression #{ (alpha.water > 0.5 ? 1025*9.81*mag(pos().z() - 0.6) : 0) #};
dimensions [ kg m^-1 s^-2 ];

field p_rgh;
create yes;

This does what it is intended to do except that it changes the BC from

=========== ================= =================
.. ground inlet outlet sides top
=========== ================= =================
p_rgh fixedFluxPressure fixedFluxPressure fixedFluxPressure empty totalPressure
=========== ================= =================


=========== ============ ============
.. ground inlet outlet sides top
=========== ============ ============
p_rgh calculated calculated calculated empty calculated
=========== ============ ============
