Load distribuiton using load wizards

Hello everyone.

I came across a problem during a simulation: when I used a load wizard to turn area loads into member loads, I selected one of the points of the area that misses the member by about 5cm (see image bellow).

After the calculation, I analised the deformation of the structure and found out that the deformations on the bars next to the one on the image above are much higher than expected, as if the load was poorly distribuited (see image bellow).

As you can see, the loads should be higher on the top beam and not on the middle beams.

Is this problem caused by poor load definition or does it have something to do with RFEM 6´s solver?
I will send the model I used for calculation.
