Odd non-preloaded fastener behavior

When applying fasteners (non-preloaded screws) to this model, strange stress results occur (see below). From what I can tell the fasteners where applied in a similar manner. So, I would expect their reactions to be the same. I have seen this behavior before on other types of fasteners (i.e. preloaded bolts). Any thoughts on where I could be making a mistake?

You'll have to add a bit more info (maybe I missed something) as you are not showing anything odd (stress plot only show 1 fastener location it seems (no sure what is being shown).

What is it you expect? you mentioned 'reactions',  Of what ? the load in each fastener due to an applied load?
