Issues with DoesIntersect and linked model rooms/spaces

I am having some trouble getting Geometry,DoesIntersect and List.Map to return valid results. I am trying to find if elements in my model are inside rooms from a linked architectural. It generally works for small test models, but when i put them on larger model it returns rooms that do not intersect with anything. I have based this script on the following you tube videos. Below I have a link to my script screen shot, and a screen shot of the results in the preview. Appreciate any insight, thank you!
