Apart from the problems rerunning that you just reported, the energy
difference should be related to the system size, e.g divide by the
number of molecules, since you have ~25000 water molecules the
difference is ~ 0.14 kJ/mol, not extreme, but incorrect nevertheless.
T and P are of course absolute.
