1D elements force Vector plot

I have a problem plotting  Vector for 1D elements force. 
My request is very simple !  request to plot such forces on cbush elements in use to simulate a junctions .

I have a Simple model Sol Nastran 106 (only large disp). I import model and results .op2 with :

1) nastran model input reader 

2) math table : advanced .

it's not the first time I've done this but it's the first time I can't see the vectors!! 

only if i see Results : 1D Vector i see only the modulus ( x,y, mag).

what am i missing?!?  the strange thing is that this type of "lack" comes to me alone for these sol 106 models… why ?!?! 
HELP me please
