Prestressed Girder Bridge Rating Issue

Hi Everyone, 

I am using LEAP Bridge software to do the bridge rating. It's a prestressed girder bridge. I did all the inputs in  geometry, material, loads, beam and I got a satisfactory results for moments and shear. But when I do rating, it does not give me the  RF. All it gives is 0.00. Is there anyone who can help me with this? 

I have attached a screenshot of the Rating results. 

Thank you in advance.

Regards, 

Romit
