None Zero-strength field vs no field

I'm measuring dose in a nontrivial geometry with an electric field. Overall, the field behaves well and gives me results that look physical. In particular, there is no difference between setting the field strength E to 0 and using E != 0 as long as E is small compared to the initial energy of my particles. However, if I remove the field completely, I see a small but statistically significant difference. That is, there is a difference between using a field with E = 0 and using no field at all. The discrepancy shows up in some of the more "hard to reach" parts of the geometry. Can any of the experts see a reason for this observation?
