Problem with TRUSS DESIGN!!!

I have read, all the related forums & watched tutorial videos. 

i have designed the truss by

a] by truss specification Done by truss specification.std

and 

b] by partial moment release .99

Done by partial moment .99.std

First of all, im facing warning in both the cases.

also the reinforcement for the rafter and bottom chord are coming heavy steel design for such a small span & less loading.

please help me out, with a correct way to design the truss.

thank you.
