Elastic Shortening and Camber in Leap Bridge Concrete

I am designing precast prestressed beams in Leap and I compared my results for elastic shortening and initial camber at midspan with hand calc and I am getting some differences.

I tried to investigate how leap is calculating and I am guessing the difference is on the way the self weight moment is calculated. Does leap uses the overall length of the beam for moment calculation at release or the center line bearing to centerline bearing distance?
