Strange behaviour by molecule in Electric field

As per my fundamental knowledge, polar molecule can rotate in electric 
field, not translate. Being more precise, here i am talking about 1 
molecule in non-periodic box. I didn't find any force to move in the field. 

Even non-polar molecule and single atom (H and Ne) are also translating in 
EF in CP2K. In the case of water cluster, the center of mass of whole 
system is translating. I have not found such behavior in other package like 

This is a very serious issue for me. Please try to suggest something if i 
am missing anything in my input.

Thank you
