Have you put your system in the middle of the cell? The charge density

not your case, we need to check your input and output to understand

I dont think it is normal, especially in the case of MP correction, as  
the correction is just on the energy. Post more details so we can look  
into it.

Btw, have you tried martyna-tuckerman?
