Displacement visualization not matching scale

Okay, I have a flat 3-layer laminate being put into 4pt bending.  Defined vertical displacement of the ends of the 2 center rolls is 5mm, end rolls constrained by a bearing support at the ends.  For reference, the laminate is 6mm thick and the rolls are 8cm diameter.  The 2 center rolls are on the top plane initially and their displacement is defined relative to the top plane.

Resulting displacement colors indicate 5mm displacement.  Deformed model  set to Truescale (also tried scale of 1 just to be sure) is hugely exaggerated.

So those deflections are NOT truescale.  If I run a video it is not even starting at the starting point shown in the first picture, it has a major initial displacement.

 

 

Any hints as to what is going on?  Why does it appear to start with a wildly deformed model before implementing the 5mm displacement?

I'm not extremely experienced with mechanical simulations so either I've overlooked something or SW has an attitude this morning.  I'm willing to accept either answer, but right now I'm clueless as to which of us is crazy.
