Why is the 2D plot cut?

Dear Fluka expert,

I am trying to simulate the absorbed energy of an x-ray source in silicon. the limitation of scoring is large, but it seems it is cut (at Y=0).
Could you please help me to fix it?
I really appreciate your kind help.

Best regards,

Your beam starts in Y=0 and it is directed towards positive Y.
