Shadow Analysis Help

I’m trying to create top view renders of a building site with accurate shadow analysis but when I turn the shadow’s on they start and finish off the edge of my site. Does anybody know a fix for this, I’ve attached the relevant file any help would be really appreciated

Can you post your 3dm file?

Thank you for your help but it somehow seems to have sorted itself out. It might’ve been because I was initially working in a 3dmbak file rather than a 3dm. Thanks for responding though
