Problem with the glass of the canopy

Hi Guys
I'm taking a little break of the big projects, so i'm working in one glider but i've a problem.
I make everything normal, and i put the part of the glass 0, and when i put the upper view the glass makes a hole in the fuselage's shadow
, why????? what am i doing wrong?????
