Simulation express - Less load, more displacement??

First up, I rarely use simulation so Im sure its me doing some thing wrong here.

I need to test some drain grates im designing for a client to make sure they are going to pass load tests. I have just noticed today after changing loads for different classes that im getting the unexpected result of more displacement with a smaller load?? Ive attached the grate, when I apply a load of 80kN it gets a maximum displacement of 4.8mm, reduce that down to 10kN and it gives me 6mm?? Obviously not what I was expecting. All I have changed is the load amount, didnt remesh or anything. Visually the stresses look different, less for the smaller load but gives a higher displacement?
