Pressure loading

Hi,

I am using PLOAD4 card image for pressure loading on surface. Pressure is applied by selecting surface. But, if I decrease pressure magnitude deflection is increasing instead of decreasing . what may be the cause for this. can anybody explain this. Also, if we apply pressure on surface how it is applied on each element.
