Sub Surface not being drawn because "base surface has less than 3 points".
Below example text output of Open Studio Sketchup Plug-In File Errors and Warnings. I have multiple of these errors after performing surface matching and intersecting of surfaces. I have visually inspected the base surfaces to be sound. What is happening?
Error: Sub Surface 395 This sub surface's base surface 'Surface 399' has less than 3 points, it cannot be drawn.
Error: Sub Surface 883 This sub surface's base surface 'Surface 2438' has less than 3 points, it cannot be drawn.
Error: Sub Surface 138 This sub surface's base surface 'Surface 1943' has less than 3 points, it cannot be drawn.

I see that the vertices for the Surface are approaching but not quite 0. I unfortunately do not have a file from before the matching with all of the information.
This is caught here (Line 63). Did you keep a copy of the original .osm file (before attempting to match/intersect surfaces)? If so, can you share it (e.g. Google Drive)? Short of sharing the file in its entirety, can you edit your question by posting the .osm file excerpts for Sub Surface 395 and Surface 399? Open the .osm file with a text editor, and copy/paste both excerpts.
