Subregion is deleted after pick-lines from filled region

Following the tutorial from BIM Voice, I created my topography and subregions by first creating filled regions on a reference level, and then tab-selecting these boundaries for my subregions.

 

Picture one shows the desired effect - road, curb and sidewalk, all sharing edges:

Picture two shows an erroneous outcome. Notice how the subregion appears void rather than filled.

I am trying to workaround by doing slightly different orders of operation, but haven't managed to find a solution yet.

Can you show the overall plan showing the entire subregion?

Not sure I understand. You created a 2D Filled Region and then created a Toposurface Subregion by tracing over the Filled Region? 

 

...not sure what we're supposed to take away from the 3D View screenshot above.  Subregions are hosted to the top of a Toposurface.  

 

...what Material is assigned to the Subregion?

Interestingly, the subregion closes successfully if I don't take the full extents. Once I select the complete extents of the curb (which is done by tab-selecting with Pick Lines on a filled region), that is when the void appears.

The screenshot of the error shows how a contour line is non-continuous over the SubRegions. In my newer post, you will notice that the contour lines correctly flow across all subregions. But in the error screenshot, there is a break in the contour line where revit has removed the topography.

Split it into to 2 subregions.

Ok, it will work! Thanks Toan.

FWIW: another approach would be to edit the Fill Region and Clipboard Copy it. Then create the Subregion boundary by Pasting from Clipboard.

I tried this too and didn't have luck with it. Site view shows selected detail item, 3d shows hole in topo.

When I split at this corner, the subregions form correctly. Otherwise, if I use the whole detail item polyline, then the void appears. Maybe it has to do with the thinness / angularity of the region.
